The main canon battery, pointing out to protect the bay from sea invasion. The cannons are all still, more or less, in place though not mounted on their slides. A couple are simply laying about in the yard sinking slowly into the dirt. In the foreground, you see a few of the huge blocks cut out of the coral and stacked and mortared to form the walls and buildings.

Like history has told many times, fixed cannon, pointing out to sea, are great to protect from a sea attack, but what about the clever invader who lands miles away and comes overland?
