The doors appear to be in roughly the same condition, the baboons' destruction notwithstanding. The entry door is wood, and reasonably sturdy, but would not hold up to a protracted assault.
Vale leads you to the well room, past a pair of angled hallways. The "well room" is covered in pale yellow tiles, and has a fairly high ceiling (25' or so). In the center of the room is a shallow (5' deep) hole, 5' in diameter; the bottom is covered in muck and wiry hair. On the ceiling above it is the well itself, which ascends higher than you're able to see. Hallways run north, south, and east out of the room.
