History set in stone
Looking at the tranquil landscape of the North York Moors, it’s difficult to believe that this was once an essential contributor to the industrial revolution, thanks to the rich natural resources found underground in this area.
There were dozens of ironstone mines within the National Park together with several short-lived blast furnace sites. Ironstone was once Britain’s principal source of iron and a key material during the industrial revolution. Much of it was found in Rosedale where the population grew from 558 to almost 3000 in just 20 years thanks to the massive development of mines and kilns. There was also a maze of underground workings under Roseberry Topping and elsewhere in the Cleveland Hills.
Look closely and you’ll notice places where alum was once quarried. Alum was used to fix dyes in textiles and make leather supple. At one time most of the English alum supply came from the fringes of the North York Moors National Park and along its coastline.
Whitby has long been associated with jet, the petrified remains of the monkey-puzzle tree from the Jurassic period. It's only found along the seven-mile stretch of the coast near Whitby and inland in a number of North York Moors valleys. Excavations show that the black stone was used as early as the Bronze Age, but jet is particularly associated with Queen Victoria and the jewellery she wore when in mourning for Prince Albert.
