Rila Monastery is on the UNESCO list of World Heritage Sites. The size of the monastery is really impressive. It’s also located in really beautiful terrain. I was told that there were "cells" for over 300 monks. I'm not sure why they refer to a monk's living quarters as a "cell", but I'm sure there's a reason. Had I wanted, I could have stayed at the monastery in a cell overnight. They rent them out to tourists. 11/2005
