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.
