The wall you face is red on its left half and black on its right. On the entrance side, the wall is white opposite the red part of the wall it faces, and yellow opposite the black section.

Running from one short wall to the other at about waist height is a wooden bar, carefully carved and drilled. This bar is pierced in two places.
