Near the village of Castlejordan, a sub-rectangular partial contour fort with a total site footprint of approximately 0.4ha is positioned in a commanding position on the NW edge of a prominent hill ridge surrounded by low-lying terrain and overlooking the Yellow River to the N. Univallate for the entire circuit, with a simple entrance gap in the NE. No evidence for any internal features on the surface. The enclosing elements have been damaged at the SW where quarrying has encroached upon the monument. The external ditch has been in-filled and is not visible at the N or W. The surviving sections of the enclosing elements are under dense tree cover. The interior is under pasture. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey mapping. Site survey by O'Brien and Sweetman in 1997.

Sub-rectangular area defined by a large earthen bank approximately 4m wide and 2.75m high (O'Brien and Sweetman 1997). There is an external ditch that is approximately 8m wide. This survives best in the E and S and is in-filled elsewhere. The SW section of the enclosing elements has been damaged by quarrying.
