Tumlu Castle, locally known as Tumlu Kale, lies on a rocky outcrop next to the village of Dumlu in the province of Adana in Turkey.
Tumlu Castle is built on a limestone outcrop rising some 150 meters above the plain. From this location it has clear intervisibility with the castles of Yilan, Toprakkale, Amuda, Anavarza and Sis. This compact but impressive garrison fort was not near one of the strategic roads or rivers in the plain, but it did flank an auxiliary trail. Also, the absence of rivers in the immediate vicinity of the castle left only 3 cisterns in the fortress to supply the needs of the garrison.
Not much is known about the history of Tumlu Castle. But from the architectural elements and masonry of the castle, it is clear that Tumlu Castle is an Armenian construction. The castle is heavily fortified with massive walls and towers which is surprisingly considering that all sides, except the east flank, are protected by near vertical cliffs, varying from 20 to 40 meters in height. It was probably built in one major building period at the end of the 12th century. In 1198 it was mentioned as being owned by a Rubenid called Thoros.
Later Tumlu Castle was occupied by the Mamluks who carried out some substantial repairs.
In 1375 the castle is said to be destroyed by the Mamluks.
At present the ruins of Tumlu Castle are freely accessible although you will have to climb the rock to get in; we had to use ropes... A very nice castle ruin in a superb location.
