Gemiler Island is dotted with several late antique church's from the 4th-6th century AD and is believed to have been the original burial site of St Nicholas, the 4th century AD Bishop of Myra. A covered processional walkway leads to the uppermost and largest church on the island which is cut into the summit of the hill. Fresco's and writing are still visible on portions of one of the lower churches. By the sea, facing the mainland and partially submerged, lie the remains of relatively small structures cut into the rock, likely houses and or shops. Large cisterns are also to be found, presumably to provide fresh water to the permanent monastic population that would have occupied the island and to thirsty pilgrims to the site.
