The Palais Garnier is a stunning 19th-century architectural masterpiece. This iconic opera house, designed by Charles Garnier, boasts opulent interiors, including the grand staircase, the grand foyer with its beautiful ceiling paintings, and the elegant salon du glacier. Visitors can explore the history and secrets of this historic building through self-guided tours or guided tours, immersing themselves in the world of opera and ballet.

Palais Garnier inspired the Phantom of the Opera, and is the setting for the famous novel, and musical. They've checked, and there is no phantom living in the watery basement (although it is truly full of water - the French firefighters use it for training!)
