Castlehowe Stone Circle is a compact Bronze Age monument formed of ten pink Shap granite boulders and a single contrasting blue stone. Measuring approximately 5 metres in diameter, the circle sits quietly in the south-east corner of a rough grass field beneath Castlehouse Scar. Despite its modest scale, it is a designated scheduled monument, recognised by Historic England for its archaeological importance within this richly prehistoric landscape.

Castlehouse Scar lies just yards from the stone circle, separated only by a bridleway and a low stone wall. Once a working quarry, the scar has since been re-landscaped and planted with young deciduous woodland, softening its industrial past. The emerging trees now frame the field edge and circle beyond, creating a subtle contrast between prehistoric settlement and more recent human alteration of the land.
