The Royal Chapel is located inside the Palace of Versailles. After the security check, it is the lower level of this chapel, and you can also go up to the second floor to see a better angle. Currently only allowed to look at the door. There are exquisite and beautiful paintings on the dome, the main altar on the first floor, and the large pipe organ on the second floor. The decoration is mainly gold and white, which is different from the extreme luxury decoration in the living area, which is more elegant and low-key. It is also the place where members of the royal family attend mass collectively. In the movie "The Peerless Queen", Marie Antoinette and the prince held their wedding here.
