This ancient system made it possible to supply water to the monastery, as well as control water level in the Svyatoye Lake that it stands on. Archeologists have never found a similar construction before. Having unearthed such a water supply system, archeologists want to deepen their excavation work, since they examined the upper level of ground only. The entire system is located at the depth of no less than 2 meters.

      The monastery was founded in 1429. With the beginning of the Soviet regime all the monks were expelled from their monastery, which was closed.
