HASANKEYF, Turkey – There was something about Hasankeyf that made visitors fall in love with the town on first sight.
Graced with mosques and shrines, it lay nestled beneath great sandstone cliffs on the banks of the Tigris River. Gardens were filled with figs and pomegranates.
The golden cliffs, honeycombed with caves, are thought to have been used in Neolithic times. An ancient fortress marked what was once the edge of the Roman Empire. The ruins of a medieval bridge recalled when the town was a trading center on the Silk Road.
Now it is all lost forever, submerged beneath the rising waters of the Ilisu Dam, the latest of President Recep Tayyip Erdogan's megaprojects, which flooded 100 miles of the Tigris River and its tributaries. The steadily expanding reservoir displaced more than 70,000 inhabitants. Unexplored archaeological riches were swallowed up along with farms and homes.
The waters have rendered Hasankeyf an irretrievable relic of the bygone civilizations that had been drawn to the valley, carved over millennia by one of the Middle East's greatest rivers.
When Erdogan turned on the first turbine of the hydroelectric dam in May, he promised that it would bring peace and prosperity to southeastern Turkey. The dam would contribute billions to the economy and irrigate thousands of hectares of farmland, he said.
Officials have emphasized that hydropower offered their greenest option when they decided to push ahead with the dam a dozen years ago, allowing Turkey to reduce its dependence on imported coal and gas.
But many who lost their homes and livelihoods are bitter and traumatized. Environmentalists and archaeologists are frustrated, too, at the loss of the valley and its treasures.
