The ruins of a small Byzantine fortified complex near the village Agios Nikolaos of Chalkidiki, at the beach Trani Ammouda on a small protrusion of sand.
Its name was “Agios Nicolaos Chrysokamaros” and it was a dependency of the monastery of Zografou in Athos Mountain (which is right across the sea, on the other side of the bay).
It was built in the 14th century. Only some ruins of the fortification remain, as well as part of the main tower. kastra.eu/castleen.php?kastro=ammouda
