Priene Castle, locally known as Priene Kalesi or Samsum Kale, lies atop a mountain, northwest of the village of Güllübahçe, in the province of Aydιn in Turkey.
Priene Castle is in origin the acropolis of the ancient Greek city of Priene, which lies beneath the ca. 200 meters high mountain, called Teloneia in Greek times, on which the acropolis was built. The acropolis was built in the mid-4th century BC. Its straight curtain walls, with square towers projecting at intervals, follow the top of the mountain, giving it a triangular plan. Centuries later during Byzantine rule a circular tower was built in front of the entrance, connected to the older fortification with curtain walls.
A nice ruin. Getting to the castle will take a walk of about an 40 minutes uphill over a dirt track. The views over the Söke plain are beautiful. Recommended.
