A University of Å·ÃÀ¿Ú±¬ÊÓƵ at Boulder research team led by history Professor Robert Hohlfelder has discovered the remains of a 1,700-year-old Christian church submerged in shallow water in the Mediterranean Sea off the coast of southern Turkey. The stone church, about 20 meters long and 10 meters wide, apparently was built sometime after 330 A.D. on the shoreline of the ancient city of Aperlae. As the shoreline subsided over the centuries due to earthquake activity, the church gradually sank about six feet into the clear Mediterranean water, said Hohlfelder.
