The Dôme des Invalides is a large former church in the centre of the Les Invalides complex. The dôme was designated to become Napoleon’s funeral place in a law dated 10 June 1840. The excavation and erection of the crypt, that heavily modified the interior of the domed church, took twenty years to complete and was finished in 1861.
Inspired by St. Peter’s Basilica in Rome, the original for all Baroque domes, the Dôme des Invalides is one of the triumphs of French Baroque architecture. Mansart raised its drum with an attic storey over its main cornice, and employed the paired columns motif in his more complicated rhythmic theme. The general programme is sculptural but tightly integrated, rich but balanced, consistently carried through, capping its vertical thrust firmly with a ribbed and hemispherical dome. The domed chapel is centrally placed to dominate the court of honour.
this is a raw scan that took 20min to make, but I think it worth sharing it :)
