Blackdown Rings

This site provides a stunning viewpoint showing the broad geological features of the South Hams. Blackdown Rings consists of an Iron Age hill fort with a Norman Motte and Bailey built within the prehistoric embankment.

The rocks underlying the site, Staddon Grits, can be seen in the commemorative stone by the site entrance. These are harder than the Devonian slates found to the north and south, so resulting in some of the highest land to the south of Dartmoor. Devon's oldest rocks, those of the Start Complex, are just visible in the distance to the south.

The landforms of the South Hams, seen from this panoramic viewpoint, can be related to the structural trends of the Devonian rocks, which generally follow an east-west orientation. However, this contrasts markedly with the north-south alignment of the deeply-cut valley of the River Avon, which flows nearby.

A permissive path runs northwards into a newly established woodland. Blackdown Rings is also very close to Andrew's Wood, an attractive Devon Wildlife Trust nature reserve.
