Foça is town and district in Turkey's İzmir Province.The town of Foça is situated at about 69 km (43 mi) north by northwest of İzmir city center. The district also has a township with own municipality named Yenifoça, also along the shore and at a distance of 20 km (12 mi) from Foça proper. For this reason, Foça itself is locally often called as Eskifoça in daily parlance. The ancient city of Phocaea is located between the two modern Foças.
Additionally, Yenifoça, taken over by the Genoese in 1275 and initially as a dowry, was the more active of the two Foças during the Middle Ages, due principally to the region's rich alum reserves, the Genoese lease over them having been preserved well into the Ottoman era.Eski Foça stretches along two bays; a larger one named Büyükdeniz ("the greater sea") and a smaller cove within that large one, named Küçükdeniz ("the smaller sea"), where the medieval castle is also located.300-boat capacity marina in Foça is recently tendered and started.
