Tre-Cefn-Isaf is a square univallate enclosure with broad ditch and slightly rounded corners, similar to other enclosures of Romano-British type in the Cardigan area. However, Tre-cefn-isaf also has a rectangular annex added on south side with a very narrow ditch, possibly a palisade trench, which is an unusual feature locally. Discovered during RCAHMW arial reconnaissance on 14 July 2003.

Geophysical survey (2004) of the southern part of the enclosure complex confirmed the presence of the ditched enclosure and hinted at the presence of a circular structure within its south-eastern angle; the east-facing entrance to the southern annex appeared to be flanked by post-pits, which would appear to confirm the interpretation of its perimeter ditch as a palisade trench.
