Limestone pavements are areas of flat, exposed and weathered limestone rock surfaces.
Most of these pavements were damaged by mining over the centuries.

The limestone rocks in these pavements were formed during the Carboniferous era some 350 million years ago.
At that time this area was under the sea.
Water running through the soil found weaknesses in the rocks that were then eroded away becoming deep fissures.
