What is recorded here

Alliganstown holds a sturdy earthen ring on a narrowed esker, preserving a circular defence with an inner bank, dry fosse and outer ridge. The earth rises like a motte when viewed from the west, while a narrow gap at the south-east admits someone who already knows the way. The esker has been quarried, yet the fort still stands above the reduced land, waiting for the footsteps that shaped it.

At the higher, S-end, of a narrow N-S esker, which has been partially quarried away. immediately N of the monument. A fairly well-preserved, raised, circular area (int diams. 22m N-S; 21m E-W; ext. diams. 55.7m N-S; 53.4m E-W) is defined by an inner earthen bank (int. H 0.6-1.3m; Wth across top 1.3-2.3m; ext H 2.7-3.9m) with an entrance gap (Wth 1.9m) at SSE, a narrow dry fosse (Wth at base 1.9-2.2m; D 0.5-1m) and by a second, low outer bank (int H 0.5-1m; Wth across top 1.2-1.7m; ext H0.4-1.9m). A raised rectangular, platform (12m N-S; 9.2m E-W) defined by a low scarp (H0.5m) occupies the internal NW quadrant, and a low triangular (max. 7.5m E-W; 6.5m N-S) projects S from the outer face of the outer bank at SSW. If viewed from the W, the monument has a high, motte-like profile, and its steep profiles and absence of a causeway crossing the fosse results in a well-defended site.
