Lisbon's Garden Hills: Aqueduct Water, Giant Trees & the Estrela Basilica

From the stone reservoir where the aqueduct ends to palm groves and cycads, a leafy village square, the parliament's old monastery, a cemetery of cypresses and Fernando Pessoa's last home

1. 1. Mãe d'Água das Amoreiras: Where the Aqueduct Ends

   Praça das Amoreiras 10, 1250-020 Lisboa, Portugal

   Stand in the small square of mulberry trees and face the heavy stone building that looks like a fortress with no windows to shoot from. To your left, the last arches of an aqueduct march in over the rooftops and simply stop, as if they had run out of breath. That is exactly where they were meant to stop.

   For centuries Lisbon was a city surrounded by water and dying of thirst. The river is salty here, the old fountains were few, and every drop had to be carried uphill. So in 1731 King João V ordered an aqueduct, the Águas Livres, the Free Waters, and the people of Lisbon paid for it through a tax on everyday goods like meat, wine and olive oil. Water began reaching the city in 1748, after travelling through stone channels from springs in the hills to the northwest.

   This building is the Mãe d'Água, the Mother of Water, the reservoir where that journey ended. The Hungarian-born architect Carlos Mardel designed it in 1746, but it was only completed in 1834, almost ninety years later. Inside, a tank roughly seven metres deep holds about five and a half thousand cubic metres of water, and a little cascade still falls into it from the channel... a sound like rain inside a cathedral. When the great earthquake of 1755 flattened the lower city, the aqueduct survived almost untouched.

   The aqueduct has a darker legend too. In the 1830s a man called Diogo Alves was said to rob walkers on its high footpath over the Alcântara valley and throw them to their deaths. He was hanged in 1841, and the story goes that his head was kept in a jar for medical study... where it still sits today.

   And the mulberries around you? They are a living fossil of industry. In the eighteenth century the Royal Silk Factory worked just down the hill, and mulberry leaves fed its silkworms, which is why this place is called Amoreiras, the mulberry trees. Follow the line of the trees downhill to Largo do Rato, two minutes away, where the aqueduct water finally reached the people.

2. 2. Largo do Rato & Its Aqueduct Fountain

   Largo do Rato, 1250-185 Lisboa, Portugal

   Let the traffic swirl past you for a moment and find the stone fountain standing calmly on the edge of the square, a baroque niche with a basin, a little pediment and no hurry at all. Cars, buses and scooters pour through Largo do Rato in every direction. The fountain has seen worse.

   This is the Chafariz do Rato, built in the 1750s and fed directly by the aqueduct gallery you just followed downhill. Its design is attributed to Carlos Mardel, the same architect as the Mãe d'Água. For the people of eighteenth-century Lisbon, fountains like this one were the whole point of the aqueduct. There was no water in the houses. The water lived here, in public, and you went to it.

   Picture the scene around 1800. A queue of women with jars, servants from the big houses, and above all the aguadeiros, the professional water carriers. Many of them were Galicians from the north of Spain, who carried small barrels on their shoulders up Lisbon's staircases and sold water by the load. They were licensed, wore numbered badges, and were called out to fight fires, because they were the only ones with water at hand.

   Water was power, too. Who got a pipe to their palace or convent, and who had to queue, was decided by the Crown. Around this square stood a convent of nuns and, just to the east, the Royal Silk Factory, founded in the 1730s and reorganised under the Marquis of Pombal after 1755... industry, faith and thirst, all drinking from the same channel.

   The water still runs through the old galleries under your feet, a hidden river of stone that crosses the neighbourhood. From here, take Rua da Escola Politécnica, the street heading east along the ridge, for about five minutes. Behind a long wall on your right, a jungle is waiting.

3. 3. Jardim Botânico de Lisboa: A Jungle Behind the Wall

   Rua da Escola Politécnica 54, 1250-102 Lisboa, Portugal

   Step through the gate beside the old Polytechnic School and the city noise drops away almost at once, replaced by birds and the dry rustle of palm fronds. In front of you the ground falls steeply, terrace after terrace, into a green valley that feels like it belongs on another continent.

   This is the Jardim Botânico de Lisboa, created from 1873 for the students of the Escola Politécnica, the school whose building you just passed. Two foreign gardeners shaped it: the German Edmond Goeze laid out the upper part, the Classe, where plants were arranged by family for teaching, and the Frenchman Jules Daveau planted the lower arboretum, the wild-looking slope below. Together they cover about four hectares, right in the middle of the city.

   Walk down among the palms and you will find giants from everywhere: dragon trees from the Atlantic islands, fig trees with roots like melted wax, and one of the finest collections of cycads in Europe. Cycads are plants that were already old when dinosaurs walked past them... they look like palms, but they belong to a lineage around three hundred million years old. Lisbon's mild winters let them grow outdoors here, which is almost impossible elsewhere in Europe.

   It is worth remembering where many of these plants came from. In the nineteenth century, a botanical garden in a colonial capital was also a tool of empire, a place to test crops from Africa, Brazil and Asia. And in March 1978 a fire swept through the old school building above, destroying much of the natural history collections kept there. The garden itself was classified as a national monument in 2010.

   Find a bench under the canopy and just listen for a minute... you are a five-minute walk from one of Lisbon's busiest squares and you can hear water and birdsong. When you are ready, climb back up to the street and head downhill to the southwest, through narrow lanes, to a quiet square hidden in the valley below. If you have a few spare minutes, make the short detour east first to the garden of Príncipe Real, where a giant cypress, always called the great cedar, has been trained over an iron frame into a living roof.

4. 4. Praça das Flores: A Village Square in the Valley

   Praça das Flores, 1200-192 Lisboa, Portugal

   Slow down as you come into the square: tall trees, a small garden in the middle, a few benches, children's voices, and pastel façades looking at each other across the leaves. After the palms and terraces of the botanical garden up on the ridge, this feels like stepping into a village that somehow got lost inside the capital.

   Praça das Flores, the Square of Flowers, sits in a fold of land between two hills. Behind you rises the ridge you just came down from; ahead, the ground climbs again towards Estrela. Lisbon is built like this everywhere, a crumpled sheet of hills and valleys, and the valleys were once streams and kitchen gardens before the city filled them with streets. That is why squares like this one feel sheltered... they are literally sitting in a hollow.

   Notice what grows in Lisbon's squares. The city is full of trees brought from far away, many of them from Brazil and Africa. The most famous are the jacarandas from South America, which turn whole avenues purple in late May and June. In spring the pavements here and all over town are covered in fallen blossom, and Lisboetas complain about the sticky mess while secretly loving it.

   This is a good square to watch how Lisbon really lives. Early in the morning, people walk their dogs and buy bread; at lunch, office workers from the parliament down the road hide here under the trees; in the evening, neighbours meet on the benches and the conversation drifts from window to window. It is the kind of place you only find by getting slightly lost.

   And it is a reminder that Lisbon's green spaces are not only grand botanical showcases. They are also these small breathing holes between the buildings, the shade where a whole street escapes the August heat. From the bottom corner of the square, walk a few minutes south and the view suddenly opens onto a white palace with a long flight of steps... the seat of Portugal's democracy.

5. 5. Palácio de São Bento: From Monastery to Parliament

   Palácio de São Bento, 1249-068 Lisboa, Portugal

   Stop at the foot of the long staircase and take in the whole white façade: columns, a triangular pediment full of sculpture, and stone lions guarding the steps. It looks like a temple of state built in one confident gesture. In fact it is a monastery wearing a costume.

   Building began here in 1598 for the Benedictine monks of São Bento da Saúde, Saint Benedict of Health, and for more than two centuries this was a place of prayer, silence and gardens. Then, in 1834, after a civil war, Portugal abolished its male religious orders. The monks left, and in the very same year the new constitutional parliament moved into their cloisters.

   So the deputies of liberal Portugal literally debated inside a monastery. After a fire in 1895 destroyed the old chamber, the architect Miguel Ventura Terra built a new one, and in the twentieth century the building received the grand neoclassical front you see now. Behind it, the monks' old gardens survive around the official residence of the prime minister.

   During the Estado Novo dictatorship, which lasted until 1974, a National Assembly met here, but it was a stage set. Opposition parties were banned, censorship was everywhere and the political police arrested critics. After the Carnation Revolution of 25 April 1974, Portugal's first free elections in half a century chose a Constituent Assembly, and on 2 April 1976 the new democratic constitution was approved in this building, the text that still governs Portugal today.

   Look at the lions once more. They have watched kings' ministers, dictators' deputies and, today, protests on the steps... and they still look slightly bored. Now turn west and climb Calçada da Estrela, the steep street with the tram rails. It is a real uphill pull of about ten minutes, but at the top a white dome is waiting for you.

6. 6. Basílica da Estrela: A Queen's Vow

   Praça da Estrela, 1200-667 Lisboa, Portugal

   Catch your breath at the top of the hill and turn to face the basilica: a white baroque façade framed by two bell towers, statues in every niche, and above it all a great pale dome that you can see from half of Lisbon. Its stone glows almost pink in the late afternoon sun.

   Every stone of this church comes from a promise. Queen Maria I, the first woman to rule Portugal in her own right, vowed that if God gave her a son and heir she would build a church to the Sacred Heart of Jesus. The prince, José, was born, and in 1779 construction began. The basilica is often described as the first church in the world dedicated to the Sacred Heart.

   But the story does not end happily. In 1788, two years before the church was finished, Prince José died of smallpox at the age of twenty-seven. The basilica was consecrated in 1790 all the same. Maria's grief, piled on other losses, is often linked to the deep melancholy and mental illness that overtook her in the following years. She later went with the court to Brazil, fleeing Napoleon's invasion, and died in Rio de Janeiro in 1816. Her body was brought home, and her tomb lies inside this church, the church of the son she lost.

   If you go inside, look for the nativity scene by the sculptor Joaquim Machado de Castro, with around five hundred little figures of cork and terracotta... shepherds, kings, animals and ordinary Lisbon street life of the eighteenth century, all crowding toward one tiny manger. And the inside of the dome, with its pale marble in pink, grey and yellow, feels like standing inside a seashell.

   There is a tender irony here: a monument to a heartbroken queen now looks out over a garden full of children. Cross the road to the green gates directly opposite. The Jardim da Estrela is the next stop, and it is only a few steps away.

7. 7. Jardim da Estrela: Lisbon's Romantic Garden

   Praça da Estrela, 1200-667 Lisboa, Portugal

   Go through the gates and follow the curving paths in, past the pond where ducks argue with pigeons over breadcrumbs. Nothing here runs in a straight line. The paths bend, the lawns roll, and the trees are planted to look as if nobody planted them at all.

   That is the whole idea. The Jardim da Estrela opened in 1852 and was laid out as a romantic garden in the English style, the fashion of the age, all winding walks and carefully staged wildness, in deliberate contrast to the geometric gardens of the baroque. Officially it is named after the poet Guerra Junqueiro, but nobody in Lisbon ever calls it that.

   Look for the giants. The garden is a collection of exotic trees from around the world, with enormous fig trees whose roots spill over the ground like poured concrete, palms, cedars and trees from South America and Australia that grow happily in Lisbon's mild, damp winters. On a hot day the air under their crowns feels noticeably cooler than on the pavement outside the gates.

   Now find the iron bandstand, the coreto, with its lacework of green-painted metal. It was made in the nineteenth century for the Passeio Público, Lisbon's first public promenade, which once ran where the Avenida da Liberdade is now. When that promenade was swept away for the new avenue, the bandstand was dismantled, and in 1936 it was rebuilt here. Military bands used to play on summer Sundays while families walked in circles in their best clothes, looking at each other.

   It is still that kind of place. Grandparents, students revising, toddlers chasing ducks, someone asleep on the grass with a newspaper over their face. Leave the garden by the northern gate, the top end away from the basilica, and turn left. Behind a high wall on the corner, among tall dark trees, lies a corner of England.

8. 8. The British Cemetery: Henry Fielding Among the Cypresses

   Rua de São Jorge 6, 1200 Lisboa, Portugal

   Ring at the gate in the high wall and step into a different silence. Dark cypresses tower over mossy headstones, paths of gravel wander between them, and most of the inscriptions are in English... names of merchants, sailors, doctors and governesses who came to Lisbon and never left.

   For a long time Protestants had nowhere to be buried in Catholic Portugal. A treaty signed in 1654 between Oliver Cromwell's England and King João IV of Portugal gave English merchants the right to their own burial ground, but it took decades before this plot was in use, in the early eighteenth century. The cypresses became so famous that Lisboetas simply called the place Os Ciprestes, the cypresses.

   Find the large stone tomb near the centre. It belongs to Henry Fielding, the author of Tom Jones, one of the founding novels of English literature. Desperately ill, he sailed to Lisbon in 1754 hoping the warm climate would save him. He arrived in August and died in October of that same year, at forty-seven. His diary of the trip, The Journal of a Voyage to Lisbon, was published after his death, grumbling, funny and very human to the end.

   Look at the dates on the stones around you and you will see Lisbon's history from the outside: port-wine families, men who came for the cork and the trade with Brazil, young people carried off by yellow fever and cholera, soldiers of the Peninsular War against Napoleon. Just a year after Fielding was buried, the 1755 earthquake would kill tens of thousands across the city below.

   In the middle of the cemetery stands St George's Church, still used by Lisbon's Anglican community. Birds are the loudest thing here. When you leave, walk west into Campo de Ourique, the neighbourhood of straight streets on the plateau above, to a leafy square where the whole district gathers.

9. 9. Jardim da Parada: The Heart of Campo de Ourique

   Jardim Teófilo Braga, Rua Almeida e Sousa, 1350 Lisboa, Portugal

   Notice how the streets have changed. After the tangled hills of Estrela, here they run straight, crossing each other at right angles, with tall nineteenth- and early twentieth-century buildings standing in disciplined rows. And in the middle of them, a square garden full of trees, kiosks, benches and dogs.

   Campo de Ourique is one of Lisbon's first planned neighbourhoods, laid out on a high, flat plateau at the end of the nineteenth century. Before the houses came, part of this open land was used by the army for drills and parades, which is why everyone calls this garden the Jardim da Parada, the parade garden, even though its official name honours the republican writer Teófilo Braga. And Ourique itself recalls the battle of 1139, when Afonso Henriques, the first king of Portugal, won his legendary victory against the Moors.

   What makes this garden special is its trees, planted to shade a whole neighbourhood's daily life: tall old trees whose crowns meet over the paths, so that the whole square sits under one green ceiling. In summer, this is the coolest place for blocks around, and you will see grandparents claiming their benches as if by inheritance.

   Campo de Ourique has a fierce local pride. People here say they are going down to Lisbon when they leave, as if this were a separate town. It has its own covered market from the 1930s, its own tram, the 28, which ends its famous ride nearby at Prazeres, and its own literary ghost, who lived just around the corner.

   That ghost spent the last fifteen years of his life in a modest flat a few blocks east of here, walking these pavements to the barber, the grocer and the tavern in a hat and round glasses that nobody noticed. Leave the garden on its eastern side and walk back along Rua Coelho da Rocha, a quiet street of shops and homes. Look for the building with a name and a poem on its walls.

10. 10. Casa Fernando Pessoa: The Poet of Many Names

    Rua Coelho da Rocha 16, 1250-088 Lisboa, Portugal

    Stand opposite number 16 and read the façade: the name Fernando Pessoa, and lines of poetry climbing the wall. It is an ordinary apartment building on an ordinary street, which is exactly the point. Portugal's greatest modern poet lived here like a clerk, because that is what he was.

    Pessoa moved into a flat here in 1920 with his mother and family, and stayed until his death in 1935. By day he wrote business letters in English and French for trading firms in the Baixa. By night, in his room, he wrote some of the strangest and most beautiful literature of the twentieth century... and almost none of it was published while he lived.

    His great invention was the heteronyms: not pen names, but whole invented poets, with their own biographies, styles and opinions, who argued with each other. Ricardo Reis, the classical doctor. Álvaro de Campos, the restless naval engineer. And Alberto Caeiro, the master of them all, a country poet who wanted only to see the world as it is, trees as trees, flowers as flowers, without thinking. After a morning of gardens, Caeiro is the right companion: he wrote that nature is parts without a whole.

    When Pessoa died, he left a wooden trunk crammed with more than twenty-five thousand sheets of paper, poems, plays, horoscopes, lists, half-finished books. Scholars are still sorting them out. His last written words, scribbled in English in hospital, were: I know not what tomorrow will bring.

    Since 1993 this house has been a cultural centre devoted to his work and to poetry, holding part of his personal library. And so the walk ends where water, trees and words meet: you began at the reservoir that gave Lisbon water, crossed its gardens, and finish at the door of a man who invented a whole crowd of poets to look at them. Tram 28 starts its long ride back across the city just a few streets away.
