The old castle of Miliopou can be found standing at an altitude of approximately 300 metres on Mt. Gerakas. Today, visitors can view the ruins of the castle and settlements that were once there. Another notable site is the Early Christian church of Taxiarchis, also known as the “Evktirio of the Archangel”, which constitutes some of the oldest remains of a church on the island. It is believed to have been first erected around the end of the fourth century A.D., and today, remains of the sanctuary’s arch, square altar, pillars and their respective capitals, can still be seen. A few metres away lie the old churches of St. Kyrikos and Ioulitas.
