Gran Teatre del Liceu - Barcelona Opera House.
Founded in 1847 on Barcelona's La Rambla, the Gran Teatre del Liceu is an opera house that has retained its role as a culture and arts centre throughout its history and one that represents one of the symbols of the city. Today, it is a publicly-owned theatre – by the Catalan Regional Government, Barcelona City Council, Barcelona Provincial Council and the Ministry of Culture – under the administration of the Fundació del Gran Teatre del Liceu, which, besides the above institutions, incorporates the Patronage Committee and the old Societat del Gran Teatre del Liceu.
