The Underground Room
A mostly-cinder blocked dormitory was surprisingly free of graffiti, and offered a nice, damp, tomb-like experience. In this sealed-up pavilion, arched wooden frames of the windows lay on the ground like graves, and a network of roots from the flora growing on the roof crept in through the walls and ceiling. A particularly thick one can be seen creeping along on the opposite wall. I thought this room was just fantastic.
