I’ve passed this park many times in the car, and each time spotted the cannon that was close to the road. I kept meaning to go back one and to take some pictures. This time I was on foot and had a camera with me.
There are actually two cannons: one up by the road and a second one down it the park. Rob Yasinsac describes one of them as follows:
A genuine Hudson River artifact, it was cast at the West Point Foundry in Cold Spring, served in the Civil War, was partly buried at the Newburgh waterfront, relocated to Fort Ontario at Oswego, and brought to Ossining in the 1980s by Peter Carpenter (a high school boy scout at the time) to replace a World War I cannon that was melted down for scrap during World War II.
I’m not entirely sure which of the cannons he is describing, but I suspect it’s the one up by the road (first and second pictures in this post).
