The Teatro Colón (Spanish) (Columbus Theatre) in Buenos Aires, Argentina, is one of the world's best known opera houses. In 2006 the theatre was closed so that work could be done to improve the inside of the building. It will probably reopen in 2010.
There had been a theatre there in the middle of the 19th century. The present building was opened in 1908. The auditorium is horseshoe-shaped and has 2,487 seats. The acoustics of the building are very good. It is in the middle of Buenos Aires.
