Damlataş Cave was discovered in 1948 during the opening of a quarry for stone to be used in the construction of the harbor. The cave is on the west coast of the historical peninsula. There is a 50-meter passage at the entrance of the cave. After the passage, which is 15 meters high, there is a cylindrical cavity. From here, one descends to the bottom of the cave. The stalactites and stalagmites of the cave, which is located in the side crystallized limestone, were formed in 15 thousand years. The cave was named Damlataş because of the drops of water that continue to drip from the stalactites.
