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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
