Considered Zenith of Military Technology
This battery, named in honor of Major General Clarence P. Townsley, a general officer in World War I, was considered the zenith of military technology and was the result of careful, long-term planning. As early as 1915, the army was eager to construct the 16-inch gun batteries at San Francisco, and by 1928, the decision had been made to install two batteries near the city, one on either side of the Golden Gate straits. By 1940, Battery Townsley was completed and its two guns installed.
How to visit Battery Townsley?
Battery Townsley is now open to the public the 1st Sunday of the month, from 12 noon to 4 PM.
Battery Townsley is located one ½ mile up from the Fort Cronkhite parking lot, following the Coastal Trail; the walk up to the battery is strenuous so please allow at least 45 minutes. If you would like to request assistance to the site on open-to-the public days, please call the Marin Headlands Visitor Center at (415) 331-1540.
You can also visit the Marin Headlands page for more information about volunteering in the battery's preservation efforts, as well as directions and other programs and activities.
