Pascal Mannaerts The Citadel, an impressive honey-colored structure overlooking the Tigris River, is one example of Hasankeyf's archaeological and religious significance.

An ancient Turkish town along the Syrian border is on the verge of destruction. But not because of war or extremism.

Hasankeyf is tucked along the banks of the Tigris River. The area is littered with history: neolithic caves, Roman ruins and medieval monuments. Yet this precious example of Mesopotamian history will almost inevitably disappear once an enormous new dam is installed.

Some 78,000 people, the majority of whom are Kurds, live in this region and will be displaced once the Ilisu Dam is finished. It’s unclear exactly when the area will be flooded, but the new structure is already more than 80 percent complete.

Pascal Mannaerts Hasankeyf's historic treasures will be submerged once the construction of the Ilisu Dam is complete.

At 12,000 years old, many say that Hasankeyf meets all the criteria to be deemed a UNESCO World Heritage site. But Turkey has not officially applied for heritage status.

Last year, Belgian photographer Pascal Mannaerts documented what could be the town’s final days. Here are some of his images.

Pascal Mannaerts Economic opportunities are rare in this region of Turkey, the site of a three-decade civil war between the Kurdistan Workers' Party (PKK) guerrilla army and the Turkish state.

Pascal Mannaerts Most of Hasankeyf's current population is Kurdish, but Assyrians/Syriacs and Arab Christian families used to live in cave houses by the river. Many of these families emigrated to France, Germany and Switzerland as the Turkish government's conflict with the PKK escalated in the 1980s.

Pascal Mannaerts Awar, 14, was born in Hasankeyf. He is Kurdish, like the majority of the people living there.
