Opéra Garnier: Guided Visit in French

To those in the know, Opéra Garnier is as much a part of the cultural fabric of Paris as Notre Dame Cathedral, the Louvre, or the Tour Eiffel. And to everyone around the world, it's known as the setting for The Phantom of the Opera . Take a guided French tour of this remarkable home of the music (of the niiiight).
See the impressive façade and its rose marble columns, check out the intricacies of the friezes, admire the auditorium's seven-ton chandelier and the Grand Foyer's mosaic-covered ceiling, and make sure to take in the temporary exhibitions.
You'll be transported to the rich elegance of yesteryear as you take a guided tour (in French) of this beautiful building.
Charles Garnier designed this opera house for Emperor Napoleon III, and construction began in 1862, but the project was held up by the discovery of an underground lake onsite. Tour groups aren't allowed down to the Phantom's lair, but considering how it turned out in Gaston Leroux's novel Phantom of the Opera , maybe that's for the best.
