The cathedral on the central square (Plaza de Armas) is a sight that ranks as high as the Palacio de La Moneda, the Presidential Palace. The original building was built between 1784 and 1805, and architect Joaquín Toesca was in charge of its construction. Other buildings surrounding the Plaza de Armas are the Central Post Office Building, which was finished in 1882, and the Palacio de la Real Audiencia de Santiago, built between 1804 and 1807. It houses the Chilean National History Museum, with 12,000 objects that can be exhibited. On the southeast corner of the square stands the green cast-iron Commercial Edwards building, which was built in 1893. East of that is the colonial building of the Casa Colorada (1769), which houses the Museum of Santiago. Close by is the Municipal Theatre of Santiago, which was built in 1857 by the French architect Brunet of Edward Baines. It was badly damaged by an earthquake in 1906. Not far from the theatre is the Subercaseaux Mansion and the National Library, one of the largest libraries of South America.
