It's Huge, It's Heavy, & It's Historic!

According to the NPS, Battery Townsley was 'a casemated battery that mounted two 16-inch caliber guns, each capable of shooting a 2,100 pound projectile 25 miles out to sea...civilians living in San Francisco knew that there were batteries in the Marin Headlands but their exact locations were not revealed.' Battery Townsley is located about a half mile from the Fort Cronkhite parking lot in Marin.
