The beautiful 'Bell Caves' of Beit Guvrin. The 60 ft tall gigantic cave complex is one of about 800 bell-shaped caves located in the area. It served as a quarry that supplied building materials to Beit Guvrin during the 7th century AD. See also the hole at the top of the cave through which the quarry was removed. Thanks to its wonderful acoustics, the Bell Caves host concerts and private celebrations.
