Military History – Lonely Sentinels
The Point Loma peninsula forms a natural protective barrier at the entrance to San Diego Bay, rising 422 feet to provide strategic views of the harbor and ocean. In 1852, the government of the United States recognized the importance of this sandstone rampart and designated the area as a military reserve. In 1899, the War Department dedicated Fort Rosecrans and built a series of gun batteries over the years. During World War I and II, military facilities on the Point provided vital coastal and harbor defense systems. Between 1918 and 1943, the Army constructed searchlight bunkers, fire control stations, and gun batteries. The largest guns were at Battery Ashburn, adjacent to the park entrance station, where two 16-inch guns could fire 2,300 pound shells nearly 30 miles out to sea.
