The home of the so-called
‘blue john’ stone, Castleton has steep narrow
streets and pretty stone cottages. But beneath
them lies the reason why this Peak district wonder
is famous the world over - an extensive system of
subterranean caves and caverns that continue to
attract thousands of tourists each year.
Most are accessed on foot but one, the Speedwell Mine, takes visitors into the bowels of the earth by boat. Only Peak Cave is a true cave because the others are man-made mines. Blue John itself is a type of fluorspar from which the Victorians made numerous items, from vases to clocks.
Rope has been made in Castleton for centuries and to mark this, brides used to be given a washing line made in the town.
