The castle is located in the village of Myrtousa, 18km from Stavroupoli. It was built at around 340 BC and 614m on a hill to control the surrounding area. In the Byzantine era in the castle were settled troops of Vasileios Voulgaroktonou, Alexios Komnenos, and other emperors of Byzantium. Today only ruins remains. The area is accessible only with a four-wheel drive vehicle.
