Pskov-Caves Monastery. Holy Dormition Pskov-Caves Monastery - one of the largest and well-known in the Russian monasteries with a long history. It was founded more than 500 years ago. The name of the monastery is due to it being in the caves. The length of the distant caves is about 200 m. They are kept at a constant temperature of about + 10° C.
