Mine Howe is an Iron Age subterranean man-made chamber dug 6 meters (20 feet) deep inside a large mound.
Its walls are lined with stones fitted to form an arch over the cavity and 29 steps lead to a rock floor.
The entrance is at the top of the small hill and there are indications of other Iron Age and earlier activity around the site.

Sections of a ditch surrounding the mound were also excavated, along with what was apparently an earthen path allowing visitors access to the site.
