SMR NO: ARM 013:029
Grid Ref: H95004294
Condition: traces only
On top of a prominent drumlin with extensive views all round. A "Fort" c.30m in diam. is marked on the OS 6" map of 1835, and traces survived, preserved in the later hedge boundaries, until these were removed in recent years. A farmhouse appears to have been build hard against the E side of the site, and the scarp now seen on the side is probably not original.
