This is the interior of the Royal Chapel at the Palace of Versailes. Begun in 1689, construction was halted due to the War of the League of Augsburg; Jules Hardouin-Mansart resumed construction in 1699. Hardouin-Mansart continued working on the project until his death in 1708, at which time his brother-in-law, Robert de Cotte, finished the project. The marble floor is beautiful and to my eye the chapel has a very modern feel, not as much ostentatious gilt as the rest of Versailles. Dedicated to Saint Louis, patron saint of the Bourbons, the chapel was consecrated in 1710. Louis XVI and Marie Antoinette were married here. The chapel was de-consecrated in the 19th century and has since served as a venue for state and private events. Musical concerts are often held in the chapel of Versailles as seen to the right.
