Inaugurated in 1875, the Palais Garnier stands as the baroque emblem of the Second Empire. Designed by Charles Garnier following an 1860 competition, it replaced the old Faubourg Le Peletier opera house after Napoleon III’s assassination attempt. Built above a former reservoir, this legendary site later inspired The Phantom of the Opera .

The eclectic architecture blends polychrome marble façades and gilded statues, while the interior’s refined opulence is revealed in the grand marble staircase, with its elegant balustrades and statues of Tragedy and Comedy. The Grand Foyer, evoking Versailles’ Hall of Mirrors, opens onto the Avenue de l’Opéra .

The horseshoe‑shaped auditorium accommodates nearly 1,900 spectators over five levels; its ceiling, restored by Marc Chagall in 1964, bursts with contemporary colours set against a classic backdrop. Behind the gilding, the library‑museum preserves sets, models and archives tracing three centuries of lyric history.

Visitors can choose self-guided or guided tours. The autonomous visit (1h30) costs €15 full price / €10 reduced. The multilingual tablet audio-guide (Revelacio) is available from €8. Entry is free for under-12s, job-seekers, disabled visitor.

Tours run daily from 10 am to 5 pm (extended to 6 pm in summer) . Tickets sell until 45–60 minutes before closing, and access to the auditorium may be restricted. Booking in advance is advised, particularly during events like the 150th anniversary festivities which may cause closures .

The atmosphere mixes solemnity and wonder: art lovers, tourists, families, and students mingle. Special thematic tours, nighttime visits, or mystery events grant access to hidden areas .
