Oval contour enclosure with a total site footprint of approximately 1.2ha surrounds a low-lying hilltop overlooking level terrain in all directions and the former lake known as Lough Dalla to the immediate NW. Bivallate for the entire circuit with the enclosing elements separated by approximately 10m, though the probable outer line is subsumed into a later field-bank. There is possibly a broad flat-bottomed ditch between the ramparts. A simple entrance break in the enclosing elements on the N depicted in the second edition Ordnance Survey maps may be original. Three other narrow breaks in the ramparts are likely to be modern. A pool is apparent in the NW section of the interior. There are no other internal features visible on the surface. Ramparts survive best at the N. The outer bank has been damaged by later field boundaries which truncate the earlier feature. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey maps.

The contour fort is depicted in first and second edition Ordnance Survey mapping. First recorded in the 6 inch first edition as a sub-rectangular enclosure. A more detailed earthwork survey as part of the second edition Ordnance Survey mapping program was undertaken in 1906.

A simple entrance gap is depicted in the second edition Ordnance Survey maps. Three other narrow breaks at the N, E and SW are modern.
| 4: | None |
| 2: | A series of breaks in the bank are apparent in aerial photographs at the N to E. These are not recorded in the Ordnance Survey maps and may therefore be modern. |

Sub-circular area defined by an internal stone bank 6m wide and 1.5m high. An external bank is positioned approximately 10m outside it and there is a possible broad flat-bottomed ditch up to 8m wide between them. The outer bank varies in size and profile. It is best preserved at the N where it measures 5m wide and 0.8m high. At the SW and E, modern field boundaries are positioned on top of the bank and have almost completely obscured the original feature. At W and NW, the outer bank has a 3m wide internal ditch.
