A town of the Zaza and Kurdish highlands, Pertek blends old stone with a changed, watery landscape.
Set in the storied country of Dersim, Pertek is a place where a flooded valley reshaped an ancient town. This profile looks at its castle, its lake, and its history.

Where Is Pertek?
Pertek lies in the south of Tunceli Province, on the northern shore of the Keban reservoir, facing the country of Elazığ across the water and the Kurdish highlands toward Bingöl to the east. The damming of the Euphrates turned the old river valley here into a broad lake, and Pertek now sits where the waters lap against the hills of southern Dersim.
Pertek Castle
The glory of Pertek is its castle. Built in the Middle Ages on a rocky outcrop above the valley, the fortress served as the stronghold of local lords who controlled this stretch of the river. When the rising waters of the Keban reservoir flooded the valley, the castle’s rock became an islet, and today the fortress appears to float on the lake — its weathered walls rising straight from the water in one of the most photographed scenes in the region. A historic mosque from the old town was carefully moved to higher ground before the flood, preserving another piece of Pertek’s heritage.
The Coming of the Lake
The great Keban Dam, built on the Euphrates in the 1970s, transformed Pertek. The reservoir drowned parts of the old valley and its villages, and the town adapted to life on a new shoreline, with ferries and roads linking it across the water. Like many communities along the dammed rivers of the region, Pertek lost some of its old landscape but gained a striking new one — a town of the lake where there had once been a town of the river.
The Dersim Country
Pertek belongs to Dersim, the historic mountain region centred on Tunceli, home to a distinctive Zaza- and Kurdish-speaking population that is largely Alevi in faith. This is a land of rugged beauty and deep, sometimes painful history, with its own traditions, music, and strong sense of identity. Pertek shares in that Dersim character, a community rooted in the highlands and in the long memory of its people.
Pertek Today
Today Pertek is a quiet Kurdish town on the Keban reservoir, drawing visitors to its lake-bound castle and its scenic setting. Fishing, farming, and tourism shape its modern life, and the restored castle stands as both a landmark and a symbol of a town that adapted to a transformed landscape. Pertek endures as one of the most beautiful corners of the Dersim country.
