The inspiration behind the Estella Opera House
PSA for everyone who doesn't know: The Estella Opera House in Lies of P is based on the Opéra Garnier in Paris.
Built from 1861 to 1875, it served as Paris's main opera house during the Belle Époque and a center of cultural life. To top things off, the Opéra Garnier is also the original setting for the story of The Phantom of the Opera: Some strange occurrences in the opera's past - such as mysterious noises coming from underground during the first performance and the unresolved accident of a chandelier counterweight crashing down and killing the concierge Madame Chomette - spawned the tale of a specter haunting the opera. The secret passageways of the cellar and rumors of a subterranean lake only fueled the myth, which was eventually used by Gaston Leroux as the basis for his famous novel.
In fact, the blazing, swinging chandelier and the access to the basement located in the same room are most likely a reference to this.
