Wookey Hole Caves

About

Wookey Hole Caves () are a series of limestone caverns, a show cave and tourist attraction in the village of Wookey Hole on the southern edge of the Mendip Hills near Wells in Somerset, England. The River Axe flows through the cave. It is a Site of Special Scientific Interest (SSSI) for both biological and geological reasons.

Wookey Hole cave is a "solutional cave", one that is formed by a process of weathering in which the natural acid in groundwater dissolves the rocks. Some water originates as rain that flows into streams on impervious rocks on the plateau before sinking at the limestone boundary into cave systems such as Swildon's Hole, Eastwater Cavern and St Cuthbert's Swallet; the rest is rain that percolates directly through the limestone. The temperature in the caves is a constant 11 °C (52 °F).

The caves were used as dens by cave hyenas. The caves have been used by both modern humans and Neanderthals over a period spanning around 45,000 years, demonstrated by the discovery of tools from the Palaeolithic period, along with butchered animal remains. Evidence of Stone and Iron Age occupation continued into Roman Britain.
