Summary

Oval contour fort of approximately 5.4ha in commanding position, overlooking the Blackwater and Bride river valleys at the eastern edge of the Nagle Mountains. Bivallate for the entire circuit with additional earthworks at possible original entrance to the WNW. Interior heavily overgrown. A large cairn is positioned at the highest point in the interior. A Food Vessel burial was identified upon the partial removal of the stones in 1832 (Borlase 1897, 13). No evidence for other internal features on the surface. The inner enclosing elements survive well throughout the majority of its circuit. It comprises a dump stone bank, maximum 1.6m in height. The outer enclosing feature is best preserved to the WSW and is of similar composition. The additional earthworks at the WNW entrance comprises 2 - 3 earthen banks and corresponding external ditches.

Landscape

Hillfort Type

An oval shaped hillfort following the contours of the hilltop is located on the E spur of the Nagle Mountains. It surrounds domed summit and offers panoramic views in all directions. The entrance is positioned on the most accessible approach at the WNW, where the slope is gradual and less sever. Carn Tighernagh overlooks the Blackwater and Bride river valleys to the east and north.

Investigation History

Stone was taken from the central cairn in the late 1832 and a Food Vessel burial was discovered (Borlase 1897, 13). Earthwork survey by The Discovery Programme in 2008.

Interior Features

Central cairn with Food Vessel burial (Borlase 1897, 13). No other features visible on the surface. Modern stone cross erected in 1958.

Entrances

Partially in-turned entrance to WNW, comprising simple break in the inner and outer enclosing elements. A series of up to 3 banks and ditches abut the outer enclosing element around this entrance and may be an attempt enhance this entrance area. Two other small, simple gaps in the inner enclosing elements are apparent to the SE and SSE.

Total Number of Breaks Through Ramparts:  
4:   None

Number of Possible Original Entrances:  
2:   None

Entrances:
1. In-turned (North west):   Partially in-turned entrance to the WNW comprising a simple break in the inner and outer enclosing elements. A series of up to 3 earthen banks and ditches surround the entrance forming additional enclosing elements.
2. Simple Gap (South east):   A simple break in SE of inner enclosing element.
3. Simple Gap (South east):   A simple break in SSE of inner enclosing element.

Enclosing Works

Inner and outer enclosing elements comprise stone rubble banks 7.5m maximum width and 1.6m in maximum height. There is evidence for exterior ditch features. The enclosing features are separated by 10 - 19m. The inner enclosing feature is well preserved through much of its circuit, however, the outer example is heavily disturbed by forestry and survives best at the WSW. At the WNW, up to 3 earthen bank and ditch features abut the outer enclosing element and surround a possible original entrance. The hillfort encloses an area of 3.21ha and has a total site footprint of 5.38ha.

Enclosed Area:
Area 1:   3.21ha.
Area 2:   5.38ha.
Total:   5.38ha.

Total Footprint Area:  5.38ha.

Ramparts

✗   None

Ramparts Form a Continuous Circuit:
✗   The inner enclosing element is complete. the outer enclosing element is destroyed in placed but likely formed a complete circuit. Up to three further enclosing elements are apparent to the WNW and are likely related to a possible original entrance here.
