Fairy fort / earthen ringfort in Jamestown (rathronan Par.)

On E-facing slope in undulating terrain, under pasture, just below crest of hill. Bivallate ringfort (int. diam. 36m N-S; 33.5m E-W) enclosed by bank (Wth 3.8m crest, 7.6m base; H above int. 0.48m; H above fosse 1.21m); wide, flat-bottomed fosse (Wth 3.9m) and substantial outer bank (Wth 3.8m crest, 6.8m base; H above fosse 2.18m; H above ext. 1.4m); outer fosse visible from SW-NE (Wth 3.6m; D above outer bank 1.45m; D above ext. 1.1m). Interior slopes to ESE. Interior grass covered, however fosse and outer bank overgrown with scrub and brambles. Inner bank slopes gently to interior. Entrance (Wth 3.4m) in E quadrant appears to have been widened as the outer bank is truncated on either side. Possible causeway although cattle trampling may have created a causeway. Field boundary depicted running NW-SE along E side of ringfort has been removed, as has townland boundary to S. A post and wire fence replaces the later and the field S of this has recently been reseeded with grass. In the SW sector the outer bank is 2.21m H above exterior with slight dip at base suggestive of an external fosse. This dip is exaggerated towards the W quadrant where the external ground level rises. External fosse continues from SW-W-N-NE. Cattle gap in W quadrant. Possible bullaun (TS076-053001-) located 11.4m E of ringfort. Compiled by: Jean Farrelly Date of upload: 26 August 2011
