The Last Blast Furnace in England's Capital of Steel A great ironworks was opened in 1839 on the south bank of the River Tees in northern England. Known as Teesside, the area became the world's ironmaking capital, with almost 120 blast furnaces operating on the riverbanks by mid-century. The site switched to steel at the end of the 19th century and played a crucial role in armament production through both world wars. The sole blast furnace remaining at Teesside was built in 1979 in Redcar, at the river's mouth. The operator, a unit of Thailand's Sahaviriya Steel Industries (SSI), has announced plans to shut the plant, eliminating 1,700 jobs and ending a long era of steel production at Teesside.

The Redcar blast furnace stands on a spit of land jutting into the North Sea, at the mouth of the Tees, as a family returns to its camp in the sand dunes after bathing in the sea. A fisherman mends the roof of his hut as the blast furnace looms behind him. Its owner, SSI, bought the plant from India's Tata Steel in 2011. The area known as South Gare, at the mouth of the Tees, is home to those who fish in this area of the North Sea.
