Gaze upward with sheer astonishment at the titanic limestone colonnades, colossal pediments, and glistening dome of the Palais de Justice, sprawling across Place Poelaert. Constructed between eighteen sixty-six and eighteen eighty-three by visionary architect Joseph Poelaert, this courthouse is larger than Saint Peter's Basilica in Rome and remains the single largest building erected anywhere in nineteenth-century Europe. The monumental structure towers more than sixty meters above the surrounding streets, its colossal square base anchored by rustic limestone masonry that evokes the imperial temples of ancient Egypt and Mesopotamia.

Poelaert sited his architectural mountain on the Galgenberg, or Gallows Hill, where medieval Brussels had executed criminals and displayed their gibbets for centuries. The monumental building covers an astonishing surface area of twenty-six thousand square meters, boasting eight interior courtyards, twenty-seven large courtrooms, and a cavernous central Salle des Pas Perdus whose dome rises over a hundred meters above the floor. Poelaert's design was so colossal that its grand staircase hall could easily swallow an entire cathedral nave, with vast marble stairways ascending toward sweeping galleries that echo with every whispered conversation.

Building this imperial colossus exacted a heavy human toll on the local population. To clear the hillside site, city authorities expropriated and demolished hundreds of working-class homes across the Marolles quarter, violently displacing thousands of impoverished families. In their fury, Marolliens coined the bitter local insult schieven architek, meaning crooked architect, which remains a colorful Brussels slur to this day.

Poelaert drove himself to complete physical and mental exhaustion overseeing the construction, suffering hallucinations and dying mysteriously in eighteen seventy-nine before seeing his masterpiece finished. Legend whispered that Marolles witches had cursed the architect for destroying their ancestral hearths and alleyways. Despite decades of perpetual scaffolding and extensive ongoing restoration efforts, the building remains a functioning palace of justice where high appellate courts and historic trials take place every single day.

Walk to the western panoramic balustrade of Place Poelaert and look out across the red rooftops of the Marolles, then head toward the glass-sided Ascenseur des Marolles.
