"Lime has long been an important material in the Cumbrian Fells and Dales. Apart from its use to bind and render stonework and decorate walls, it has been invaluable for improving the fertility of acidic soils. Limestone was burnt in kilns wherever fuel and raw limestone could be brought together easily. There are remains of hundreds of lime kilns - both large and small around Cumbria. Typically the kiln was set into the side of a hill, so that carts could deliver limestone and firewood to the top. After burning slowly for at least 24 hours, the calcinated limestone, quicklime, was removed at the bottom, mainly for use on local fields."

This is a classic kiln on the edge of the ancient village of Warton, just over the border in Lancashire. It utilised the adjacent rock from Warton Crag. It is in a good state with steps leading down to the stoke hole - you can even go in it! Great views over Carnforth and out to the bay.
Park almost opposite in a handy layby. Also opposite is an entrance into Warton Crag woods, which provide good walking options - great spot for geohounds.
