The walls of this ten foot square tunnel are made of the same mottled

grey-shade stone as the rest of the area. Sounds seem to echo eerily

here, and occasionally you think you catch a glimpse of movement out

of the corner of your eye. You feel vaguely disoriented here, and have

some trouble making out exactly where you are sometimes. There is a

small brass plaque upon the southern wall, set at eye level.
