Peel Castle - The Round Battery
The Round Battery was built on the Horse Rock, at the base of the current breakwater. It is a three gun battery, the gun ports having internal and external splay. Two of the guns cover the entrance to the bay and the third (now a doorway) covered the one point on the island where a landing could be made at low tide.
On top of the gun ports is a small arms platform which could also carry wall guns.
