The blue key is in a similar situation but there is absolutely no marking whatsoever. One of the chambers has an automap that reveals the location of the red key, which is hidden in a secret. The path to the north is a series of functionally identical rooms with monster cages in the center and pillars on the sides and it's pretty blah.
There's a not-so-Wolf-ish staircase leading to a basement with what I assume is a swimming pool. The opening segment is okay as far as Wolfenstein 3D stuff goes.
