A bit of a strange one this in the middle of a public park and no-one seems to know much about it, as I havn’t really found many references to Hawksclough. Me and Rivington Pike (a fellow member of TMA) who also had vaguely heard of it decided to find it.
What we found does seem to be the site that’s on the map, its earthworks quite prominent, just no-one seems to know its there! This monuments purpose and meaning has been sadly forgotten but after all this time it still remains there on the hill for all to rediscover.
