The Palais Garnier is a opera house, which was built from 1861 to 1875 for the Paris Opera. The architect was Charles Garnier (1825–1898). It was originally called the Salle des Capucines because of its location on the Boulevard des Capucines in the 9th arrondissement of Paris, but soon became known as the Palais Garnier in recognition of its opulence and its architect, Charles Garnier. The theatre is also often referred to as the Opéra Garnier, and historically was known as the Opéra de Paris or simply the Opéra, as it was the primary home of the Paris Opera and its associated Paris Opera Ballet until 1989, when the Opéra Bastille opened at the Place de la Bastille. The Paris Opera now mainly uses the Palais Garnier for ballet.
The Palais Garnier is one of the most famous opera houses in the worlkd. This is at least partly due to its use as the setting for Gaston Leroux's 1910 novel The Phantom of the Opera and, especially, the novel's subsequent adaptations in films and Andrew Lloyd Webber's popular 1986 musical.
The Palais Garnier also houses the Bibliothèque-Musée de l'Opéra de Paris (Paris Opera Library-Museum). Although the Library-Museum is no longer managed by the Opera and is part of the Bibliothèque nationale de France, the museum is included in unaccompanied tours of the Palais Garnier.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
