A hillfort enclosing the southern end of Pilsdon Pen. The earthworks form an irregular oval enclosure consisting of two banks and ditches, and enclose an area of around 7¾ acres. Where the slope is less steep or absent there is an interval between the inner and the outer systems. There appear to have been three original entrances to the hillfort. A square earthwork in the centre is a pillow mound.
