One of the oldest foot trails in the Presidio, Lovers' Lane is an easy, one-mile walk. U.S. soldiers used the trail to visit their lovers and family in San Francisco.

Built in 1864, it displays Italianate and Greek Revival architectural styles. Constructed during the Civil War, it is one of the oldest standing buildings on the Presidio. The original structure was modified by adding wings and enclosing the porches. In 1897, an octagonal surgical tower with windows on all sides was added to provide a well-lit operating room.

The flagpole in Pershing Square (at the Main Post) marks the site of a disastrous 1915 fire that destroyed the residence and killed the wife and three daughters of General John "Black Jack" Pershing of World War I fame. Just east lies the site of the original Spanish presidio, built in 1776 on this windswept slope. A boulder by the sidewalk approximates the northwest corner of the original Presidio, which formed a square about 300 feet (100 m) on each side. Two bronze cannons at this site, forged in the 1600s, used to be mounted at Castillo de San Joaquin, a fort built at the point overlooking the Golden Gate. They are among the oldest cannon in North America.
Information on points of interest and Presidio history is available at the Visitor Center. Several videos can be viewed in the theater and a bookstore offers topical books and other media.

Established in 1898 to care for sick and wounded soldiers, it is the Army's oldest named general hospital and during WWII it became the largest Army hospital in the country. Today the complex is home to Lucasfilm and lots of Star Wars fans make the pilgrimage there each year. You won't get inside unless you know someone.
