The assistant keeper’s quarters were directly above the head keeper’s quarters and beneath the watch room. The assistant keeper suffered a lack of privacy, since anyone going up the the watch room had to pass through his room to get to the steel ladder leading to the next deck.
The assistant keepers’ quarters also marks the transition from brick construction back to cast iron. The brick wall here is about 20 inches in thickness. The watch room and lantern room continue the more traditional cast iron construction. Another marked difference the head keepers’ quarters is the lack of windows: the assistant keeper’s quarters used portholes similar to those in a ship. The main supporting column that runs through the lighthouse from the basement to the ceiling of the assistant keeper’s quarters also ends here, with six shims, like large washers, used at the top of the column to snug it up against the ceiling, which is also the floor of the watch room. Like the head keeper’s quarters, there is also the outline of a hole in the ceiling and floor adjacent to the center column, through which the weight and cable from the lens clockwork passed.
Furnishings, like those of the head keeper, were likely standard government issue. The assistant keeper did not have a walk-in closet like the head keeper because the stairs beneath which the closets were built ended at the assistant keeper’s door. He did have the same cupboard as the head keeper and almost certainly had a chest of drawers, along with his personal bag or trunk, for additional storage.
The assistant keeper’s quarters are now used as a exhibit room, with diagrams, photographs, and a lens on exhibit that give visitors insight into the lighthouse’s history and function.
