Arpaz Castle, locally known as Arpaz Kalesi, lies in the village of Esenköy, south of the city of Nazili, in the province of Aydιn in Turkey.
Arpaz Castle was built in the first half of the 19th century by the local Bey (an Ottoman Lord) Hacı Hasan. He had shortly before returned from Rhodes and probably had the castle built after the medieval Naillac Tower he had seen there. The castle incorporated earlier buildings, dating back to the 17th and 18th century, which had been burned in 1829.
The castle is a tower house, entrance was through a door on the first floor, which was protected by a drawbridge. It is surrounded by outbuildings and a wall with buttresses, like at Cincin Castle.
Arpaz Castle is now situated on the grounds of a farm and its interior can not be visited. The top of the tower is now home to several storks.
