By November 1860, Ro de Fleury had completed what he thought would be the crowning achievement of his career, and was also working on a commission from the city to design the façades of other buildings lining the new square to ensure their harmony. On September 29, 1860, an Imperial Decree officially designated the site for the new Opera, which was to eventually occupy 12,000 square meters (1.2 ha). The new building would help address the awkward convergence of the streets at this location, and the location was economical in terms of land value. By March, Haussmann had settled on a proposed Rho de Fleury site next to the Boulevard des Capucines, although this decision was not publicly announced until 1860. This anxiety, as well as inadequate facilities and the temporary nature of the theater, made the construction of a new state opera house all the more urgent. The limited access to the Salle Le Peletier emphasized the need for a separate, more secure entrance for the head of state. On January 14, 1858, an attempt was made to assassinate Emperor Napoleon III at the entrance to the Salle Le Peletier. With the establishment of the Second Empire in 1852 and the appointment of Georges-Eugène Haussmann as Prefect of the Seine in June 1853, interest in the new opera house revived. The site was later occupied by the Grand Hotel Louvre (partially designed by Charles Rho de Fleury). However, with the revolution of 1848, Rambuteau was fired, and interest in building a new opera house faded. By 1847, Claude-Philibert de Rambuteau, Prefect of the Seine, had chosen a site on the east side of the Palais Royal as part of the extension of Rue Rivoli. Charles Rohault de Fleury, who was appointed the opera’s official architect in 1846, made various studies of suitable sites and projects. Since then, there has been a need for a new permanent building. In 1821, the Paris Opera moved into a temporary building known as the Salle Le Peletier, on Rue Le Peletier. The Palais Garnier also houses the Bibliothèque-Musée de l’Opéra de Paris (Library-Museum of the Paris Opera), which is operated by the National Library of France and is included in unaccompanied tours of the Palais Garnier. Another factor is that among the buildings built in Paris during the Second Empire, more same is the most expensive, only one, which is “undoubtedly a masterpiece of the first rank.” Is this at least partly due to the fact that it was used as an opera house? setting for Gaston Leroux’s 1910 novel The Phantom of the Opera and, in particular, subsequent film adaptations of the novel in films and the popular musical of 1986. The Palais Garnier has been called “probably the most famous opera house in the world, a symbol of Paris such as the Notre Dame Cathedral, the Louvre or the Sacré Coeur Basilica”.
