Trendle Ring

Trendle Ring (or Trundle Ring) is a late prehistoric earthwork on the Quantock Hills near Bicknoller in Somerset, England, and is a Scheduled Monument. Covering 0.8 hectares, it is surrounded by a single rampart with a ditch and has one entrance on the east, uphill side. Its purpose remains debated -- variously described as a fort, settlement, livestock enclosure, or hill-slope enclosure. The word 'trendle' means circle, making it a tautological place name. In 2013 it was added to the Heritage at Risk Register due to vulnerability to plant growth.
