Work on this enormous mock Romano-Byzantine edifice began in 1877. It was commissioned after the nation's defeat by Prussia in 1870, voted for by the Assemblée Nationale and built from public subscription. Finally completed in 1914, it was consecrated in 1919 - by which time a jumble of architects had succeeded Paul Abadie, winner of the original competition. The interior boasts lavish mosaics.
