The Main Post is the heart of the Presidio. It marks the site of a Spanish garrison established here in 1776. This historic site served as a Spanish fortification, then fell under Mexican control, and finally became an important U.S. Army post in 1847. The Presidio's oldest existing buildings are found on the Main Post.
