Avşar Castle, locally known as Avşar Kalesi or just as Myus, lies on a low hill, north the village of the same name, in the province of Aydιn in Turkey.
Avşar Castle was built by Byzantines on the site of the ancient Greek city of Myus. This city was situated on a small peninsula in the Agean sea. But due to the silting up of the mouth of the Maeander river (now called the Büyük Menderes river) over the centuries, the site is now situated some 25 km from the coast on the Söke plain. Of the city itself not much remains but 2 temple foundations and a part of a pillar near the castle ruin. I could not find any historical information related to the castle itself. If you know more, please mail me.
Avşar Castle was built out of rubble-work masonry. It has a rectangular plan with a gate tower in its eastern curtain wall. The curtain walls have nice slender arches on the inside, which I thought resembled the walls of Keçi Castle a bit.
A beautiful ruin. Getting to the castle will take a walk of about 25 min from the nearest road over a dirt track. The site is freely accessible.
