Sited on a hill, 807 feet above the sea level, Warbstow Barrows is one of the largest and best preserved earthworks in the County.
It has two ramparts, each with two entrances, the inner area being 370 by 450 feet. The outer rampart averages 15 feet in height, with an external ditch 15 feet wide.
In the middle is a barrow, called the ‘Giants’ grave, and sometimes ‘King Arthur’s grave’.
