 The European rock is usually identified with an islet, about wide and long, which stands about off the shore of a village called Rumeli Feneri ('Lighthouse of Rumeli), and is connected to it by a modern concrete jetty.At its highest point, there is an ancient altar known as the Pillar of Pompey, though it has nothing to do with Pompey.Dionysius of Byzantium mentions a Roman shrine to Apollo on one of the Cyanean Rocks, and the 16th-century French traveller Petrus Gyllius thought the altar was a remnant of that shrine.
