Earthworks of a later Prehistoric type settlement consisting of at least four roundhouses. These are 6.0-7.0m across and are represented by circular banks up to 0.6m high. There are indications of two other roundhouses in the same general area and a midden mound of seashells lies a little way to the north-east.
These features may be associated with the old field boundaries and cultivation terraces that occur across Penmon Park (NPRN 302861).
