Walking to the end of the village you will find the beautiful tabernacle of Saint Merkourios (17th century) built over the ruins of an older Byzantine temple. Saint Merkourios is the patron saint of Istrios and that is why the village's central church is also dedicated to him. Surrounded by pinewoods, olive groves and vines, the village of Istrios brings visitors close to nature. The region around Istrios, the dam of Apolakkia's and Profilia, is of particular natural beauty. It is a shelter for wild life and it is protected under the "NATURA 2000" European Network. If you enjoy walking, there are a lot of paths and rural roads. In the "Kipolistis" region, visitors will discover waterfalls, a forest with pines and will enjoy the region's rich fauna and flora.
