Indicated

Situated at the base of a S-facing slope in an undulating valley with a stream c. 10m W of the site running N-S. A small hillock has been artificially scarped to create a large, trapezoidal, grass-covered platform (66m max. N-S; 29.5m min. N-S; 63m E-W) enclosed by a low, earth and gravel bank (Wth 1.3m; int. H 0.35m; ext. H 1.57m) which falls steeply to the exterior and is relatively insignificant internally. The bank is levelled at NE and the S end of the E side has been denuded by modern agriculture. There is no fosse visible around the base of the platform though there is a slight dip (Wth c. 1m) which is quite wet. A fulacht fia (TN033-029002) is incorporated into the NE angle of the site and another (TN033-029003) lies immediately N of the site.
