Sol-Iletsk (Russian: Соль-Иле́цк) is a town in Orenburg Oblast, Russia, located on the right bank of the Ilek River (Ural's tributary), 77km (48miles) south of Orenburg, the administrative center of the oblast. Population: 22,000 (1975); 11,802 (1897).
The climate is arid, sharply continental.
It was founded in the 17th century as a Cossack settlement. In the mid-18th century, it was renamed Iletskaya Zashchita (Russian: Илецкая защита) due to the construction of fortifications. The name was then changed to Iletsk (Russian: Илецк) in the 19th century. In 1945, the town was given its present name. A thick bed of rocksalt is worked near this town (hence, the word "Russian: соль" (sol) in the town's name, which means "salt" in Russian). The place has also been known as a balneological resort for its mineral waters, salt, mud, and brine baths, and its kumis cures.
Within the framework of administrative divisions, Sol-Iletsk serves as the administrative center of Sol-Iletsky District, even though it is not a part of it. As an administrative division, it is incorporated separately as the Town of Sol-Iletsk[2] —an administrative unit with the status equal to that of the districts. As a municipal division, the territories of the Town of Sol-Iletsk and of Sol-Iletsky District are incorporated as Sol-Iletsky Urban Okrug.[3]
Sol-Iletsk houses what is commonly called the Black Dolphin Prison.[4]
