Church of the Immaculate Conception
The Church of the Immaculate Conception was built from 1855 by the architect Pierre Bossan who realized the basilica of Fourvière. It has many points in common with the famous building in Lyon. It is also the very first parish in France to be placed under the patronage of the Immaculate Conception.
About this building
The church is characterized among other things by its dome, which was fashionable at the time for orientalist architects, but less so for its architect Bossan. The plan of the church, a Latin cross centred on an octagonal dome with side chapels and an ambulatory, was also used for the Basilica of Ars. Another peculiarity, structural this one, is to have made the mass of the vaults carried by groups of very thin columns, seemingly out of proportion, thanks to the use of the vault in landfill. This technical innovation was later taken up again in the Basilica of Notre-Dame de Fourvière.
