Visit the Opéra Royal, Versailles Court Theatre
The inauguration of the opera house was in May 1770 in celebration of the marriage of Louis XVI to Marie Antoinette. At the time of construction it was the largest theater in Europe and was an exemplification of the finest design, and burned 10,000 candles in a single setting. It is built entirely of wood but is painted in such a way to resemble marble, called faux marble.
What makes this it bucket list worthy?
Theater in general, and this theater in particular, was hugely important in the French enlightenment, which eventually lead to the French Revolution.
