Assemblée Nationale — Palais Bourbon

The Palais Bourbon in Paris, home to France's National Assembly, features an 1806 grand facade built seventeen degrees off-axis from the actual palace to align with surrounding landmarks. Originally constructed in 1722 for Louise Françoise de Bourbon, it briefly housed the École Polytechnique in 1794 before hosting parliament in 1798. Its library ceiling displays twenty-two paintings completed by Eugène Delacroix between 1838 and 1848.

Why is the facade of the Palais Bourbon in Paris tilted seventeen degrees off-axis?

Look across the river. See those twelve grand columns gazing back at you from across the Seine? That is the Palais Bourbon... home of France's National Assembly. But here is what most people don't know. That spectacular facade? It's a Lie. A magnificent, deliberate, architectural lie.......... The building behind it is seventeen degrees Off Axis from the colonnade you see. Why? Because in eighteen oh six, Napoleon commissioned architect Bernard Poyet not to align the facade with the actual palace... but to align it with the pont de la Concorde and the Madeleine church across the river. The facade is literally a stage set... a screen bolted onto an older building, tilted to create the Illusion of perfect urban symmetry.......... And it gets better. Those thirty-two steps leading up to the columns? They serve no architectural purpose whatsoever. Poyet designed them purely to raise the colonnade high enough to be visible from the opposite bank, despite the hump of the bridge blocking the view. The entire thing is an immense trompe-l'oeil!......... And legend has it... Napoleon Hated it. Despite all this ingenuity built in his honor, he reportedly said he wished he were still an artillery officer... so he could aim his Cannons at what he called "this ridiculous screen."

...... But the palace's history goes far deeper than Napoleon. It was built in seventeen twenty-two for Louise Fransoise de Bourbon, the legitimized daughter of King Louis the Fourteenth and his mistress, madame de Montespan. A royal pleasure house with gardens stretching all the way to the Seine.......... Then came the Revolution. The palace was confiscated. And here is a detail that will surprise you. Before it became a parliament, this building briefly housed the future école Polytechnique! In seventeen ninety-four, the stables and orangery of this aristocratic palace were converted into chemistry laboratories for France's most elite engineering school. Students studied in the very rooms where a king's daughter once held court.......... Only a year later, the Council of Five Hundred moved in... and they chose their opening date with Chilling precision. January twenty-first, seventeen ninety-eight. The fifth anniversary of the execution of Louis the Sixteenth. The members arrived dressed in Roman togas, in true neoclassical fashion... only to discover the chamber had terrible acoustics and almost no ventilation.......... Inside today, if you could peer past those columns, you would find Eugène Delacroix's most ambitious work... twenty-two paintings across the library ceiling, stretching themes from Theology to Poetry, from the dawn of Greek civilization to the fall of Rome. He spent a full Decade on them, from eighteen thirty-eight to eighteen forty-eight.
