The “small” cave church of St Mark and St Simon the tanner's Hall. used as the winter church because it is completely covered.This huge cave was discovered in 1979 full of hundreds of tons of rocks at a height of 17 meters from the ground. After several years of hard work and prayer, they began to find a path in order to start removing the rocks and finally it was prepared to contain 2 levels. The upper storey is St Simon's Hall which accommodates 2000 people in spiritual meetings. The walls are decorated with many wonderful pictures engraved on the rocks representing scenes from the Bible.
