Soledar, the town in Ukraine’s eastern region of Donetsk, is home to Europe’s largest salt deposits: a vast, cavernous network of underground tunnels extending for about 200 kilometres. Such is the scale of the mines that geologists claim that less than five per cent of the seam has been removed since industrial mining began in 1881. Explored reserves amount to about five billion tonnes. © Artemsil Ukraine: The Battle for Soledar’s Salt Mines Russians took control of the symbolic town with commercial as well as strategic purposes in mind. 9 Mar 23
