Above is an amazing video from Bastion A on the second tier of the Fort, taken on a Sunday afternoon in August. The video takes a tour from Deer Island, crossing the President Roads and moving South to Blue Hills. On the way through the video, you can see Boston Harbor Lighthouse, Nix Mate, Long Island, Spectacle Island, Thompson Island, and Blue Hills. In the foreground at the end of the video is a view of the 15-inch Rodman Gun. This spectacular view gives you a very good idea why, in 1631, they selected this site to protect the Neck of Boston
