Palais d’Iéna

The Palais d’Iéna is recognizable by its sweeping, triangular form and a series of giant, fluted concrete columns that line the avenue. Designed by the architect Auguste Perret and constructed between nineteen thirty-seven and nineteen forty-six, it was built as the National Museum of Public Works for the nineteen thirty-seven Universal Exhibition. The building stands on a triangular plot and features a striking rotunda at its apex, where the two wings meet.
