Greeting Card Portrait - Tunstead Quarry, Great Rocks Dale

The largest producer of limestone in the Peak District is Tunstead Quarry. This quarry, along with the adjacent Old Moor Quarry, produces around 5.5 million tonnes of limestone annually. It is the largest producer of high purity industrial limestone in Europe. In terms of output, it rivals the large limestone 'superquarries' of the Mendip Hills in Somerset which primarily exist to supply construction aggregate to south-east England. Tunstead is a big local employer; 400 people work at the site and a larger number are employed by contractors and local businesses which provide goods and services to this major industrial operation.
