Bandera street leads toward the building of the Santiago Stock Exchange (the ''Bolsa de Comercio''), completed in 1917, the Club de la Unión (opened in 1925), the Universidad de Chile (1872), and toward the oldest churchhouse in the city, the San Francisco Church (constructed between 1586 and 1628), with its Marian statue of the ''Virgen del Socorro'' ("Our Lady of Help"), which was brought to Chile by Pedro de Valdivia. North of the ''Plaza de Armas'' ("Square of Arms," where the colonial militia was mustered) are the Paseo Puente, the Santo Domingo Church (1771), and the Central Market (Mercado Central), an ornamental iron building. Also in downtown Santiago is the Torre Entel, a 127.4-meter-high television tower with observation deck completed in 1974; the tower serves as a communication center for the communications company, ENTEL Chile.
