After the Earthquake: The Baixa Pombalina and the Lisbon of 1755

How Lisbon rose from the disaster of 1 November 1755: the lost royal palace, the grid of the Baixa, earthquake-proof timber cages, the Inquisition's square, the Carmo ruins and the revolution of 25 April 1974

1. 1. Praça do Comércio: Where the Royal Palace Fell

   Praça do Comércio, 1100-148 Lisboa, Portugal

   Stand in this vast square with the river at your back, the bronze king on horseback in the middle, and yellow arcaded buildings wrapping around you on three sides. It is so orderly, so calm... and every line of it was drawn because of a catastrophe.

   Before 1755 this was the Terreiro do Paço, the Palace Yard. King Manuel the First had moved the royal residence down here in the early 1500s, and the Ribeira Palace grew into one of the grandest in Europe, with a royal library of tens of thousands of books, archives of the voyages, paintings by great masters, and a brand-new opera house opened only months before the end. On the morning of 1 November 1755, All Saints' Day, with the churches full, the ground began to shake.

   The shaking came in waves over several minutes, and churches, palaces and houses came down across the city. Many survivors ran to the open quay here, away from falling walls. Then the river drew back, and not long after, the sea came in. Fires started by candles and kitchen stoves burned for days. Tens of thousands of people died in Lisbon. The palace, the library and the opera were gone.

   The king, José the First, was out at Belém with his family and survived. Afterwards, it is said, he could never again bear to sleep under a stone roof. The man who took charge was his minister Sebastião José de Carvalho e Melo, later the Marquis of Pombal. He sent a questionnaire to every parish: how long did the shaking last, what happened to the wells, how did the sea behave? Those answers are often called one of the first scientific studies of an earthquake.

   The bronze rider is José the First, cast by the sculptor Machado de Castro and unveiled in 1775, and the square was renamed for commerce rather than for kings. In this same square, in 1908, King Carlos and his heir were shot dead in their carriage, a blow from which the monarchy never recovered. Now walk east along the arcades and down Rua da Alfândega to a church doorway that somehow survived the end of the world.

2. 2. Igreja da Conceição Velha: The Doorway That Survived

   Rua da Alfândega, 1100 Lisboa, Portugal

   Stop in front of the side doorway of this church and let your eyes climb its stone: twisted columns, coiled ropes, leaves, angels and armillary spheres, every inch carved like lace. Now step back and notice how strange it looks, this flamboyant thing set into a sober eighteenth-century street.

   That portal is a survivor. It belongs to the early 1500s, the reign of King Manuel the First, and its style, full of ropes and sea symbols, is called Manueline after him. When the earthquake flattened almost everything around it in 1755, this doorway stayed standing. So what you are looking at is one of the very few glimpses of the old, pre-earthquake Baixa still in its place.

   The building began as the church of the Misericórdia, the charitable brotherhood founded in 1498 under the patronage of Queen Leonor, widow of King João the Second, to care for the sick, prisoners and the poor. Look up at the carving above the door. The Virgin of Mercy spreads her cloak over a crowd of kneeling figures, and among them people usually identify a pope, King Manuel and Queen Leonor herself.

   After the disaster, the church was rebuilt around the survivor, and a parish that had lost its own church moved in, bringing the name it carries today: Conceição Velha, the old church of the Conception. That was how the rebuilding worked... the city was redrawn, and congregations, saints and names were shuffled into whatever walls were left standing.

   Picture the street before 1755: narrow, crooked, full of shops and the smell of the river, with this doorway as just one ornament among dozens. Everything else you will see on this walk was built after the shaking stopped. This is the before. Now head west and then north, into the grid, along Rua da Madalena and across to Rua dos Fanqueiros, to a church whose façade lines up perfectly with the street.

3. 3. São Nicolau and Rua dos Fanqueiros: A City Drawn With a Ruler

   Rua da Vitória, 1100 Lisboa, Portugal

   Look along the street in both directions: straight as a ruler, the same height of building, the same rhythm of windows, the same iron balconies on the first floor, all the way to the end. And then notice the church of São Nicolau, which does not stand in a grand square, but slots into the line of houses like one more neighbour.

   That modesty was policy. After 1755, the Baixa was not patched up, it was redesigned from scratch. The ageing chief engineer of the kingdom, Manuel da Maia, laid out the options: rebuild the old maze, widen a few streets, or start again. Pombal chose to start again, and the plan drawn by the architects Eugénio dos Santos and Carlos Mardel gave Lisbon this rational grid between the river and the Rossio.

   Churches had to fit the plan, not the other way round. São Nicolau, a parish that goes back to the Middle Ages, was rebuilt slowly over the following decades with its front aligned to the street. Pombal's critics complained that the new streets were absurdly wide. He is said to have answered that one day they would seem too narrow. Watch the traffic squeezing past and judge for yourself.

   Now read the street signs. The new grid was given to the trades. Rua dos Fanqueiros was for the cloth and linen dealers, Rua do Ouro for the goldsmiths, Rua da Prata for the silversmiths, Rua dos Correeiros for the saddlers and leather workers, Rua dos Douradores for the gilders. Rua da Prata was originally named Rua Bela da Rainha, the Queen's Beautiful Street, before silver won.

   One more detail: look at the rooftops. Between the buildings, the dividing walls rise above the roofs. Those are firewalls, there to stop flames from jumping from house to house, because in 1755 it was the fire, as much as the shaking, that destroyed the city. Now walk north up Rua dos Fanqueiros, straight and gently rising, all the way to a big open square with a king on horseback.

4. 4. Praça da Figueira: The Hospital Under the Square

   Praça da Figueira, 1100 Lisboa, Portugal

   Walk into the middle of the square, among the pigeons and the trams, and look up at the castle sitting on its hill above the rooftops. The king on horseback here is João the First, and he looks rather pleased with himself.

   He has reason to. João the First won the throne in the crisis of 1383 to 1385, defeated Castile at the battle of Aljubarrota, and married Philippa of Lancaster, sealing the alliance with England that Portugal still likes to call the oldest in the world. His sons included Henry, the prince the English call the Navigator. The statue, though, is recent: it was set up in 1971.

   What lies beneath your feet is far more interesting. Before 1755, much of this square and the eastern side of the Rossio was covered by the Hospital Real de Todos-os-Santos, the Royal Hospital of All Saints. King João the Second laid its first stone in 1492, and it became one of the great hospitals of Renaissance Europe, a whole complex with wards, a church and gardens. The earthquake and the fires that followed left it in ruins.

   It vanished so completely that later generations half forgot it was here. Then, when the ground was dug up in the twentieth century, and again during construction work around the year 2000, archaeologists found walls, burials and objects from the old hospital. The square you are standing on is, in a sense, a lid on a lost building.

   After the disaster, the empty space became a market, and for decades a great iron and glass market hall stood here, until it was demolished in 1949. Figueira means fig tree, perhaps from a tree that once grew on the spot, a very homely name for a place with such a story. Now cross the north-western corner of the square towards the bell tower of a church whose stones, as you will see, still carry the marks of fire.

5. 5. Igreja de São Domingos: The Church That Kept Its Scars

   Largo de São Domingos, 1100 Lisboa, Portugal

   Step inside, let your eyes adjust to the dim red light, and look at the columns. They are cracked, blistered and blackened, the stone peeled away in great flakes as if the church had been flayed. Nobody has painted over it. That was the point.

   The Dominicans founded this church in the thirteenth century, and its history is heavy. In April 1506, during a service here, someone claimed to see a miraculous light on a crucifix. A New Christian, a converted Jew, voiced doubt, and he was dragged out and killed. Stirred up by preaching friars, mobs then hunted New Christians through the streets of Lisbon for three days. Somewhere between two and four thousand people were murdered. King Manuel later punished the city and had friars executed.

   Thirty years later the Inquisition came to Portugal, and the Dominicans were at its heart. Processions of the condemned set out from this part of the city on their way to the autos-da-fé, the public ceremonies where sentences were read, and some victims were burned. In the square outside, a memorial set up in 2008 remembers the victims of 1506 and calls Lisbon a city of tolerance, which is partly a promise.

   The earthquake of 1755 brought much of the church down, and it was rebuilt. Then, on 13 August 1959, fire broke out and raced through the interior, destroying the altars and paintings. When it finally reopened in 1994, the decision was made to keep the damage visible: the scorched stone, the broken surfaces, the ghost of the gold.

   It is one of the most powerful interiors in Lisbon precisely because it refuses to look new. Outside, the little square is a lively meeting place, where you will often hear the languages of Portugal's former African colonies. Now step out and walk a few metres west into the long square beyond, the Rossio, and stop in front of the theatre with the columns.

6. 6. Rossio: The Inquisition's Square and the Wavy Pavement

   Praça Dom Pedro IV, 1100 Lisboa, Portugal

   Look down first. The black and white stones under your feet ripple in long waves from one end of the square to the other, so that on a hot day you feel slightly seasick crossing it. Then look up, past the two bronze fountains and the tall column, to the pale neoclassical theatre closing the north side.

   This is the Rossio, officially Praça Dom Pedro the Fourth, and for centuries it was the true centre of Lisbon, the place of markets, bullfights, celebrations and executions. The wavy pavement is called Mar Largo, the wide sea. It was laid in the 1840s, and the story goes that much of the work was done by prisoners. It became the model for the black and white calçada portuguesa you now see all over the Portuguese-speaking world.

   Now the theatre. The Teatro Nacional Dona Maria the Second opened in 1846 on the site of the Palácio dos Estaus, a fifteenth-century palace built to lodge foreign dignitaries. From the sixteenth century, that palace became the headquarters of the Inquisition in Lisbon. In this square, autos-da-fé were staged before crowds: the condemned were paraded, sentences were read, and some were handed over to be burned. A theatre now stands where the tribunal sat, which is one way for a city to answer its past.

   The Inquisition's palace survived 1755 only to burn in 1836, which made room for the theatre. And the theatre itself burned in 1964, its interior gutted, and reopened only in 1978. Look at the statue on top of the pediment: Gil Vicente, the court poet counted as the father of Portuguese theatre.

   The man on the column is King Pedro the Fourth, who was also the first emperor of Brazil. A stubborn rumour claims the statue was really made for the emperor Maximilian of Mexico and bought second-hand after he was shot... a story historians have firmly rejected, but Lisbon keeps telling it anyway. Now walk south down Rua Augusta, the broad pedestrian street, and stop about halfway down, where Rua da Vitória crosses it.

7. 7. Rua Augusta: The Cage Inside the Walls

   Rua Augusta, 1100 Lisboa, Portugal

   Stop in the middle of Rua Augusta, among the street performers and café tables, and look at the buildings on either side: four or five storeys, identical windows, wrought-iron balconies, shops at street level. They look like ordinary city blocks. Inside the walls, they are machines.

   After 1755, the engineers of the rebuilding asked a simple question: how do you make a house that will not kill the people inside it the next time? Their answer was the gaiola pombalina, the Pombaline cage. Inside the masonry walls, builders set a three-dimensional frame of timber, braced with diagonal crosses. When the ground shakes, the wooden lattice flexes and holds the building together, instead of letting the stone simply collapse on the people inside.

   The story goes that the system was tested by building a wooden model and having soldiers march around it to imitate an earthquake. Whether or not that happened exactly so, the gaiola is counted among the earliest building systems in Europe designed against earthquakes. And the parts were standardised: doors, window frames, stonework and ironwork were made to measure in series, almost like an eighteenth-century flat-pack city.

   Now think about what lies under your feet. The Baixa sits in a low valley where a stream once ran down to the river, on soft, waterlogged ground. So the new blocks were set on thousands of pine piles driven deep into the mud. As long as they stay wet and away from the air, the wood does not rot, and the piles have been holding up these streets for more than two centuries. A few blocks south, in the basement of a bank, an archaeological site shows some of them beside Roman fish-salting tanks.

   The cage has a weakness, though, and it is us. Over the years, owners have cut away timber to open up shop fronts and added heavy extra floors on top, and engineers worry about how many of these buildings would still behave as designed if the ground shook again. The street's name, Augusta, honours the majesty of the king who reigned when it was rebuilt. Now carry on south down Rua Augusta towards the great arch at the end, and stop just beneath it.

8. 8. Arco da Rua Augusta: A Triumph That Took a Century

   Rua Augusta 2, 1100-053 Lisboa, Portugal

   Stand right under the arch and look up into the great vault, then step out on the square side and turn around to see the whole thing: columns, statues, a clock, and on top a crowned woman holding out two wreaths. It frames the river at one end and the whole grid of the Baixa at the other, like a theatre's proscenium.

   An arch here was part of the idea from the beginning, a ceremonial gateway between the new commercial square and the new city behind it. But Lisbon took its time. Designs came and went, money ran short, and the arch you see was only completed in 1873, more than a century after the earthquake, to a design by the architect Veríssimo da Costa.

   The figure on top is Glory, crowning Valour and Genius, by the French sculptor Célestin Anatole Calmels. Below, four Portuguese heroes stand guard: Viriathus, the Lusitanian chief who fought Rome, Nuno Álvares Pereira, the general of Aljubarrota, Vasco da Gama, who sailed to India, and the Marquis of Pombal himself, finally given a place on the monument to the city he rebuilt. The two reclining figures represent Portugal's great rivers, the Tagus and the Douro.

   Now read the Latin inscription. It says, roughly, to the virtues of the greatest, so that they may serve as a lesson to all, dedicated at public expense. It is a confident sentence for a city that had nearly been wiped out, and that is precisely why it was carved.

   Since 2013, a lift and a narrow stair take visitors up to the top of the arch, and the view from there, straight up Rua Augusta to the Rossio and the castle, shows you the whole logic of the plan in a single glance. From above, you see what the planners saw on paper... a city laid out in straight lines on the ruins of a maze. Now turn west along Rua do Comércio, parallel to the square, for a couple of blocks, to the square of the city hall.

9. 9. Praça do Município: The Balcony of the Republic

   Praça do Município, 1100-365 Lisboa, Portugal

   Face the long neoclassical building with the flags and the central balcony, then turn to the twisted white column in the middle of the square, spiralling up like a stick of barley sugar. Around you, the wavy pavement radiates out from its base.

   This is Lisbon's city hall, the Paços do Concelho. The council's old building went down in 1755, and a new one was raised as part of the reconstruction. Then, in 1863, that one burned too, and the building you see is the rebuilding that followed. Lisbon has a habit of losing its buildings to earthquakes and fire and simply drawing them again, a little grander each time.

   Now look at the balcony. On the morning of 5 October 1910, after a short revolt in the streets, republican leaders stepped out onto it and proclaimed the end of the monarchy. The young king, Manuel the Second, sailed into exile in England. Every year on that date the Portuguese president comes back to this balcony, because this is where the Republic was born.

   The twisted column is the pelourinho, the pillory. For centuries every Portuguese town with its own charter had one, a symbol of municipal justice, and some had iron hooks where offenders were displayed or punished. This one was raised during the reconstruction years, more elegant than menacing, but its message was the same: here the city governs itself.

   Think about the sequence you have now walked through. The king's palace destroyed in 1755, a minister rebuilding the city with ruthless efficiency, a king and his heir shot dead in the great square in 1908, and then, two years later, the monarchy proclaimed over from this balcony. From here, walk north up Rua do Ouro, the old street of the goldsmiths, for a good four hundred metres, until a tall iron tower appears on your left.

10. 10. Elevador de Santa Justa: An Iron Lace Lift to the Ruins

    Rua do Ouro, 1150-060 Lisboa, Portugal

    Tilt your head right back and follow the tower of grey iron up into the sky, all pointed arches and filigree, with a little walkway at the top leaping across to the hillside. It looks like a Gothic cathedral that decided to become a machine.

    The Elevador de Santa Justa opened in 1902 to solve a very Lisbon problem: the flat, rebuilt Baixa sits in a valley, and the Chiado and the Carmo sit on a cliff directly above it. Rather than climb, you would ride. At first the lift was powered by steam, and a few years later, in 1907, it switched to electricity. The tower stands about forty-five metres tall.

    Nearly everyone in Lisbon will tell you it was designed by Gustave Eiffel, or by one of his pupils. It was not. Its engineer was Raoul Mesnier du Ponsard, born in Porto to a French family, who also built several of Lisbon's funiculars. He certainly admired the iron architecture of his age, and the legend of Eiffel has proved impossible to kill.

    Notice the style. The neo-Gothic arches were a deliberate choice, and they rhyme with what waits at the top of the walkway: the Gothic ruins of the Carmo church, left open to the sky since the earthquake. So the lift was a modern iron machine dressed to match a medieval ruin, a very nineteenth-century way to make peace between progress and memory.

    From the walkway at the top you can see the whole rebuilt grid laid out at your feet, Rossio on one side, the river on the other, the castle across the valley. It is the view the Pombaline planners never had, the plan seen from above, finished. Now ride up, or if the queue is long, climb the steps and lanes behind the tower, a short but steep ascent, to the square in front of the ruined church of the Carmo.

11. 11. Convento do Carmo and Largo do Carmo: A Ruin and a Revolution

    Largo do Carmo, 1200-092 Lisboa, Portugal

    Stand in the shady square with its old fountain and jacaranda trees, then look at the Gothic church front on one side and, through its doors, at stone arches that hold up nothing but the sky. Pigeons sit where the roof should be.

    The Convento do Carmo was founded in 1389 by Nuno Álvares Pereira, the general who had saved Portugal's independence at Aljubarrota. Late in life he gave up his wealth, became a Carmelite friar here, and died in 1431. In 2009 he was declared a saint. Then on 1 November 1755 the vaults of his great church came crashing down. Rebuilding was begun and then abandoned, and the nave was left open to the sky, the most famous ruin of the earthquake.

    Walk inside if you can. Since 1864 the ruin has housed an archaeological museum, so tombs, carved stones and curiosities sit under the open arches, rain falling on them as it has fallen since that All Saints' morning. No museum label says more about 1755 than this missing roof.

    Now turn to the barracks on the square, still a base of the Republican National Guard. On 25 April 1974, the head of the dictatorship, Marcelo Caetano, took refuge here as army rebels moved through Lisbon. Captain Salgueiro Maia brought his troops into this square and surrounded the building, and thousands of people poured in to watch, climbing on the fountain and the trees. By evening Caetano had surrendered power to General Spínola, ending nearly half a century of dictatorship.

    That day gave the revolution its name. In the streets nearby, people pushed red carnations into the barrels of soldiers' rifles, and it became the Carnation Revolution. One square, two of the great turning points of Portuguese history: the day the city fell and the day the country stood up. Now leave the square by Calçada do Sacramento, the short lane running downhill, to Rua Garrett, the elegant main street of the Chiado.

12. 12. Rua Garrett and the Chiado Fire of 1988

    Rua Garrett, 1200 Lisboa, Portugal

    Stand on Rua Garrett where it meets Rua do Carmo and look around: polished shop fronts, stucco façades in soft colours, iron balconies, everything looking as if it had been here for two hundred years. Some of it has. Some of it is barely thirty years old, and the trick is that you cannot easily tell which.

    In the early hours of 25 August 1988, a fire broke out in a department store on Rua do Carmo, just below you. It spread through the old Pombaline blocks with terrifying speed, the timber floors and frames burning like kindling. Fire engines struggled to get into the narrow streets. By the time it was out, much of the area between here and the Baixa had been gutted, with a couple of dozen buildings destroyed or damaged and two people dead. For Lisbon, it felt like a small echo of 1755.

    The city asked one of its most respected architects, Álvaro Siza Vieira, to lead the reconstruction. Siza made a choice that surprised many people: no showy new landmark. He kept the Pombaline façades, rebuilt the volumes and rooflines of the eighteenth-century plan, and put modern interiors behind them, with new passages and courtyards opening up the blocks.

    So the Chiado was rebuilt twice in the same spirit, first by Pombal's engineers after the earthquake and then by Siza after the fire, both times on the principle that the city's form mattered more than any single building. Siza also designed the Baixa-Chiado metro station below, which links the low city and the high city underground. The street itself is named after Almeida Garrett, the Romantic writer who helped found the national theatre you saw in the Rossio.

    Here the walk ends. You started where a palace vanished and a city was redrawn with a ruler, you passed the scars of fire and Inquisition, the ruins of the Carmo and the square of the revolution, and you finish in a street that burned and came back looking as if nothing had happened. That is the Baixa's whole story... Lisbon falls down, and Lisbon draws itself again.
