Castercliff

Castercliff is an Iron Age multivallate hillfort situated close to the towns of Nelson and Colne in Lancashire, Northern England [1]. On the upper part of the hill, triple rubble ramparts up to 1.5 metres high, separated by ditches of similar depth, surround the site on all sides except the north [1]. On this side the defences consist mainly of a single rampart and ditch, but some short lengths of triple rampart and ditch are also found here [1]. The inner rampart may have been timber-laced and revetted with stone and enclosed an oval area measuring approximately 115 by 76 metres [1]. The summit of the hill is 280 metres above sea level and the surrounding ground falls rapidly on all sides except the south east [1]. The hillfort has been damaged by coal mining with old bell pits evident both inside and around the site [1].
