The Plaza de Armas is the main square of Santiago, the capital of Chile. It is the centerpiece of the initial layout of Santiago, which has a square grid pattern. This urban design was accomplished by Pedro de Gamboa, which was appointed by Pedro de Valdivia in 1541.
Surrounding the square are some historic buildings, including the Metropolitan Cathedral of Santiago, Central Post Office Building, Palacio de la Real Audiencia de Santiago, and the building that serves as the seat of local government for Santiago, which was formerly occupied by the Cabildo of the city before being remodeled.
