Undated earthwork mound.


Annotated Ordnance Survey maps maintained by PMC Kermode (Manx Museum director 1922-1932) and W Cubbon (Manx Museum director 1932-1940) bear the note 'Fort' (Kermode) and 'Circle' (Cubbon) within this field.


Cubbon's annotation is more correctly located, a little to the north of Kermode's.


Aerial and ground survey show the presence of an almost perfectly circular mound or platform, defined by a ditch which in places is both well-defined and waterlogged. The platform has a diameter of just over 30m, and the ditch a width of 5 to 6m.


The field bears the local name of Yn Aaigh Greddagh ('the parched flat').
