Recorded monuments

• LI042-002 Hilltop enclosure
  Description

  In pasture, on crest of broad E-W rise. Monument, depicted as embanked circular enclosure (diam. c. 70m) on 1923 OS 6-inch map, has been levelled. No trace of monument evident when inspected. Area immediately N of site is covered by coniferous plantation. The monument was recently described in the Atlas of Hillforts of Britain and Ireland as following; 'Circular multiple enclosure with a total site footprint of approximately 0.5ha positioned at the crest of a broad E-W rise on SE facing slopes of hilltop and overlooking the interchange between two distinctive valleys running N-S and E-W. Bivallate on the W side, the enclosing elements probably originally formed two complete circuits. There are no obvious entrance features. No evidence for any internal activity on the surface. The fort has been completely levelled in recent times. Visible in aerial photographs prior to 1995 and in historic mapping, the enclosing elements comprised a complete outer rampart which survives well throughout the circuit and an inner, concentric bank. The E half of this enclosing element is not apparent in aerial photographs or in the historic mapping. The interior is covered in dense scrub. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey mapping.'
