Agio Galas is one of the most significant archeological sites of the island. On the craggy slope below the homonym village lies the Agio Galas Cave. It was named after the white diffluent liquid that drips like milk in the cave and is said to have healing properties. Moreover, it is a complexion of three caves and you will be impressed by the formation of the limestone due to the pluvial water. The largest cavern was inhabited during the Middle and Late Neolithic Era. Several archeological findings were found in the cave: earthen vessels (bottles, jars), stone or bony tools and jewelry made of stones, bones and shells. Panagia Agiogalousena (13^th-14^th centuries) lies at the entrance of the middle cave and the church of Agia Anna (11^th-12^th centuries) in its interior. The third cave with the stalagmites supplements this subterranean beauty, where history, religion and nature are united.
