Shown on both the 1843 and 1854 OS maps of Huddersfield is feature named as a ‘Camp’ at Crosland Hill, on the fields between Butternab Woods and what is now Johnson’s Quarry.
The fields there have been built on now, but I remember them before they were developed (used to play footy on them as a teenager), but I don’t remember any identifiable earthworks at the time.
According to the map it was an oval enclosure (maybe 100 yards long by 50 wide). I’d be bold as to hazard a guess that it was an Iron Age camp (although it could equally be as late as Saxon), as it would have had a good view of Castle Hill Hillfort. As Castle Hill was abandoned around 400BC, I’d suggest a date before this. But as houses now stand on the spot and no excavation was done, I guess we’ll never know.
Delves Wood Road runs up the side of where it once stood and Woodleigh Grove would probably be smack, bang in the middle of it.
Shame I didn’t realise it was there before they built on the spot!
