Devil's Chapel Scowles (grid reference SO606045) is a 44.79-hectare (110.7-acre) biological Site of Special Scientific Interest in Gloucestershire, notified England, in 1998.

[1][2] The site lies in the Forest of Dean and has four units of assessment by Natural England.

The pits, holes and features called scowles occur in the centre of the Dean and normally contain iron ore, which gave rise to mining in the area.

Habitats range from endangered limestone grassland to acid heathland, which are conservation priorities in Gloucestershire's Biodiversity Action Plan.

Of prime importance is that the scowle areas support threatened species of bat.
