Yeni-Kale

Yeni-Kale was built by Ottoman Turks in 1699–1706 on the Kerch peninsula that belonged to the Crimean Khanate. The name Yenikale means New Fortress in Turkish . The fortress was built under the guidance of Goloppo, who was an Italian convert to Islam. Several French engineers also took part in the construction.
Yeni-Kale was armed with powerful cannons and took an important strategical place on the coast of Kerch Strait. The fortress occupied area of 25,000 m² and had two powder-magazines, arsenal, water reservoir, living houses, bath-house and mosque. About 800 Turkish and 300 Crimean Tatar soldiers were garrisoned in Yeni-Kale. The weak spot of the fortress was a lack of drinking water in the area, so an underground water-pipe was made to bring water from a source located several kilometres away from the fortress. Yeni-Kale also served as a residence of the pasha.
