Megalo Chorio ( Tilos ) , is the impressive capital, located on the north side of the island and 6 miles northeast of Livadia. It is built on the slope of a hill on top of which are the ruins of the Castle of the Knights.
Until the early 18th century the village was within the castle walls. In the same place where today we find the Castle of the Knights,the acropolis of the ancient city existed. The ruins of the temple of Apollo nearby, are reminiscent of the long history of the island.
