Buenos Aires‘s first opera house, the Teatro Colón, opened in 1857. By 1888, the theater was closed, as the city needed a larger and more modern facility. Construction on the new building began in 1889 and took almost 20 years to complete. The project was begun by Italian architect Francesco Tamburini, taken over by his assistant Vittorio Meano upon Tamburini’s death, and completed by Belgian architect Jules Dormal upon Meano’s assassination. It is in the heart of the city.

The majestic building, completed in 1908, was built on classical European style and in particular that of the French and Italian Renaissance. The building is vast, measuring 2,439 sq m (26,250 square feet). Several entrances allow access for both performers and opera-goers. The main entrance hall has a white marble floor that leads to a wide staircase.

The auditorium is horseshoe-shaped, has 2,487 seats (slightly more than the Royal Opera House in Covent Garden, London), standing room for 500, and a stage which is 20 m (60 f) wide, 15 m (45 f) high, and 20 m (60 f) deep. The low-rise building has 6 floors above ground and 3 below ground, 7 elevators with a facade of applied masonry. Suspended from its frescoed dome is a 7-m (23 f), burnished bronze chandelier with 700 light bulbs.

The Colon's acoustics are considered to be so good as to place it in the top five performance venues in the world. Luciano Pavarotti held a similar opinion.
