5,000-year-old salt mines in Turkey are still in use today - PHOTO

From the surface there is nothing special about the hilly countryside around the city of Cankiri in Turkey.However 1,300ft below ground is a stunning salt mine which was first dug by primitive humans around 5,000 years ago.Despite its incredible age the mine is still in use today and produces more then 500 tonnes of salt each year which is used in cooking and for a range of souvenirs.According to a 1971-79 survey there is still more than 1billion tonnes of ore left in the mine, which is extracted using machines and underground blasting.These pictures were taken by Melih Sular, 32, who was guided through the caves by Murat Danaci as part of the National Geographic photography contest.According to a 1971-79 survey there is still more than 1billion tonnes of ore left in the mine, which is extracted using machines and underground blasting.These pictures were taken by Melih Sular, 32, who was guided through the caves by Murat Danaci as part of the National Geographic photography contest.'The cave is cool and scentless, which is because it is a very old salt cave. The walls are all made of rock salt and the texture is varied because of the digging machines used.'He added: 'I've never seen anything like it before. The most striking part of the caves is the old gallery, which were dug by Hittites.'It's interesting because they dug this gallery with simple tools and their own hands, unlike today's methods.'While temperatures in the city regularly reach 92 Fahrenheit (33C), the mercury never strays much above 59 degrees (15C) inside the ancient caves.The Hitties were an ancient race who built an empire in the Middle East which covered most of modern-day central Turkey, northern Syria and Iraq and flourished between 1,400 and 1,200BC.They were famous for their skill in building and making chariots and wrote in a hieroglyphic-type language called cuneiform.They were eventually destroyed after several costly wars, particularly a defeat to the army of Ramses II, pharaoh of the Egyptians. Competition for succession of the throne also drained their resources.Today the mine has 16 workers and contains a small canteen, a mosque, repair room, workshop and a first aid room.All the ore extracted from the mine, which measures in at around 90 per cent purity, is taken by diggers to nearby railway tracks where it is transported to a factory for processing.There is so much salt contained in the ground around the mine that it appears around the edge of a nearby lake after being dissolved into the water.(dailymail.co.uk)ANN.Az
