Our visit to Baker Beach included something I hadn’t realized was there. The coast around the entrance to the Golden Gate is dotted with old gun batteries and it turns out that Baker Beach is another location. This gun emplacement is called Battery Chamberlain. While the concrete installations are still pretty much intact, the majority of the battery is long gone. However, one of the gun positions has been preserved and the gun is installed.
I took a quick look around while one of the guys who looks after things was working on the gun mechanism. He was changing the elevation of the gun and working on the mechanism that aligns the gun. I was able to peer down the barrel and take a look at the rifling. Apparently they run tours periodically but I just took a quick mooch around before heading on my way.
