What is recorded here

Thoan Bann may have been a rath or cashel in County Derry, but no certain date or builder is known. The name suggests a fortified place rather than an ordinary field, and the possibility of a fortification gives the site more weight than silence.

The official Northern Ireland record identifies this as Site of Thoan Bann fortification (possible) - rath or cashel. Recorded period: UNCERTAIN. The official map point was placed at the centre of the recorded archaeological site from the source map reference.

The monument record does not grant public access. Check the route and ask the landowner before entering private land.
