The Colón Theatre is one of the most famous opera houses in the world. Located on 9 de Julio Avenue, in the heart of the city, the theatre has 2,367 seats and standing room for 1,000. With perfect acoustics and modern stage areas, this interior design featured a rich scarlet and gold decor. The cupola contains frescoes painted in 1966 by the renowned 20th century artist Raúl Soldi during renovation work. This cornerstone was laid in 1889 under the direction of architects Francesco Tamburini and Angelo Ferrari, who designed a modern theatre in the Italian style. However, due to local arguments regarding location and other factors, construction dragged on for twenty years before the house was completed by Julio Dormal in 1908.

It opened in may 1908 with a performance of Verdi’s Aida and it quickly became a world-famous operatic centre rivaling La Scala and the Metropolitan Opera. Over the years, the theatre has hosted such of the greatest names.

The theatre is presently undergoing several phases of remodeling and production activities ceased at the end of October 2006 to allow full refurbishment to take place in time for its re-opening on 25 May 2008, the theatre's 100th Anniversary.
