Presidio of San Francisco Main Post

The Main Post of the Presidio of San Francisco, with its visitor center at 210 Lincoln Boulevard, is the historic core of a military installation that began as a Spanish garrison in 1776 and remained a base under Spain, Mexico and the United States for 218 years before becoming part of Golden Gate National Recreation Area in 1994. The Spanish founded the Presidio on the bay shore to guard the entrance to San Francisco Bay, and the site passed to Mexico in 1822 and to the United States in 1846. Under the US Army it grew into a major West Coast post, sheltering refugees after the 1906 earthquake and serving as a staging point in several wars. The Main Post is organized around a large Parade Ground, bordered by rows of brick barracks and officers' quarters in Georgian Revival and Victorian styles built mostly in the 1880s to 1890s. Visitors can see the Officers' Club, which incorporates adobe walls traced to the original Spanish presidio, along with the Presidio Visitor Center and the Archaeology Lab, where finds from digs on the post are interpreted. Outdoor markers, a walking trail network and the Pershing Square area tell the story chronologically from the Ohlone and Yelamu peoples through the Spanish, Mexican and American military eras. After the Army departed in 1994, the Presidio Trust took on stewardship, reusing many historic buildings as offices, museums, restaurants and housing while preserving their exteriors, and restoring native habitat across the wider park. The grounds are open daily and free, while the visitor center keeps shorter hours of roughly 10:00 AM to 4:00 PM, so check presidio.gov before going. A visit can range from a short stroll around the Parade Ground to a half-day exploring the post, nearby Crissy Field and the Golden Gate waterfront. The setting among eucalyptus and cypress groves, with views toward the bay, makes the Main Post a popular combination of history and outdoor recreation in San Francisco, California.
