Keep of Dol Amroth Castle(nw, w and n)
This is the Keep of Dol Amroth, a "castle within the castle." It is the last stronghold of the forces defending the castle, a final place of refuge should attackers force their way inside the castle walls. This stone bastion is designed for easy defense by a small number of soldiers. It was obviously NOT built for spaciousness or comfort. The entire keep is no more than fifty feet across in either direction and is bare of furnishings. Hay covers much of the stone floor, particularly in the corners. The thick stone walls have a narrow wooden catwalk running around them fifteen feet above the ground. Archer slits pierce the walls every ten feet along the walkway. A high ceiling made of tin is held up by heavy timber spars and supports.
The only obvious exits are northwest, west and north.
