Summary

Large and complex contour hillfort located on prominent hill overlooking N coast at Redruth. Very steep surrounding slopes to N, moderate to S. Affected by Neolithic origins as tor enclosure, with multi-phased activity from Mesolithic to post-medieval. East and central summits enclosed by stony ramparts linked by paired ramparts across both and south flanks of the hill. Iron Age round houses proved in saddle between the two tops. On E summit wall links granite outcrops enclosing c. 0.7 ha, within which level platforms and terraces, seen by low walling. Circuit continuous. Possible SW entrance. Higher central W summit enclosed by ramparts and summits linked by boulder-built ramparts, with ditches to S, so enclosing c. 2.8 ha. Further, outer circuit of ramparts, damaged by mine workings to S, has ramparts enclosing c. 14 ha. Series of hut circles lie between summits. On tor enclosure surrounding E summit, pits, postholes and hearths on platforms found. Possibly attacked in the Neolithic as 750 leaf arrowheads and extensive burning unearthed. Also fragments of 550 South-Western style vessels. Outworks join the E and central summits. Different walling styles suggest phasing. but range similar to causewayed enclosures. C14 dates from E summit c. 3670-3535 cal BC, and suggested that, overall, Neolithic activity ended 3495-3080 cal BC. Much excavated from 19th century. Moorland site. Fair condition despite mining activity. On 1st Ed. OS map (1880).
