Allianoi Ancient City and Yortanli Dam, Turkey


The Turkish State Hydraulic Works devised a plan in 1994 to dam the Ilya River with Yortanli Dam, creating a reservoir in order to increase agricultural productivity in the region. Yortanl Dam was constructed for irrigation purposes and the ancient ruins and Roman spa of Allianoi was discovered when routine excavation on the proposed dam site took place, in 1998. The site dates as far back as the second century and features exquisite architecture, mosaics and sculptures. Despite pleas from archaeologists, environmental groups and the European Union, the Turkish government went ahead with the proposed flooding and although several court cases were won, Allianoi was submerged by dam waters on 31.12.2010 by getting around the law.

Other comments:Following the referendum on the constitutional change of 12.09.2010, which brought many changed in the judiciary structure of the courts, even won cases have nearly been taken back by the courts concerning environmental lawsuits. This situation seriously reappears, especially in the case of Allianoi and other hydroelectric power plants.
