H 0.5m; generally: Wth 4-4.3m; int. H 0.45-0.9m; ext. H 1.1-1.3m), with internal facing stones E-SE, which is separated by a flat-bottomed fosse (Wth of base 4.3-5.7m; D 0.1-0.3m) from the base of a destroyed bank (Wth 4.7-5.8m; ext. H 0.1-0.4m), which cannot be traced S-SW. This is surrounded by a flat-bottomed fosse (Wth of base 4.2-4.8m) and a third outer overgrown bank (Wth 3.5-5,5m; int. H 0.5m; ext. H 0.7-0.9m) which survives SE-W-NW and can be traced as a low mound (Wth 5-6.2m; int. H 0.1-0.2m; ext. H 0.1-0.4m) at N and NE-SE. There is a widened entrance (Wth 5m) through the inner bank at SE (max. ext. diam. 84.2m E-W; 83.8m N-S). Compiled by: Michael Moore Date of upload: 24 August 2010

A second fosse (Wth of top 3-4m; Wth of base 2.4-2.9m; ext. D 0.4m) and a third overgrown bank (Wth 2-3m; ext. H 0.2-0.3m) survive WSW-NNE.
