This is a large circular enclosure (50 m in diameter) surrounded by earthworks. The site is on the eastern slope of Alnwick Moor, overlooked by higher ground. The earth banks and ditches that encircle it are partly destroyed, but can still be seen well-preserved on the south side. At this point the ditches bulge out to form a second outer area between the banks. This area is reached by a causeway across the outer bank. This may have been the main entrance to the site. Although there are piles of stone inside the site these are probably not hut circles. It has been suggested that sites like this were used as places to protect cattle and other animals. It is not certain what period this site belongs to, but it is most likely to be Iron Age This is a Scheduled Monument protected by law.
