Presidio San Francisco

View towards Alcatraz.

'The Presidio of San Francisco served as an almost continuously active military
garrison for more than 200 years under the flags of three nations. Established in 1776
by Spanish soldiers and colonists, the Presidio became part of Mexico when that
nation gained its independence in 1821. The first United States troops arrived at the
post in 1846, and the Presidio began to develop into the country's most important
Army post on the West Coast. Today the Presidio's architectural, historic, natural and
scenic landscapes are preserved and protected as a national park for all to enjoy.'
