GALILEE, ISRAEL—A man-made pile of basalt boulders has been found on the floor of the Sea of Galilee. The monument is circular in shape, and rises 32 feet high. Scientists from the Israel Antiquities Authority think the structure may have been built in the third millennium B.C., when other megalithic structures, associated with fortified settlements, were built. Another theory suggests that the stones were dropped into the water to construct a gathering place for fish.
