The National Monuments Service's description
Around a natural knoll (dims c. 32m NE-SW; c. 28m NW-SE; H 2m at SE to 3m at NW) on a gentle S-facing slope of the Rathcroghan plateau. Circular grass-covered area (int. diam. c. 74m) defined by an earthen bank (at E: Wth 7.4m; int. H 1.4m; ext. H 2.2m) and outer fosse (at W: Wth of top 9.3m; Wth of base 4.5m; D 0.4m), which is obscured by a modern road bank E-S (max. ext. diam. c.110m N-S). The probable entrance (Wth 6m) is at SSE. Geophysical testing failed to record evidence of any internal structures or activities, apart from what might be an episode of burning on the summit of the knoll (Waddell et al. 2009, 58-66). Described as a possible ring-barrow (Herity 1983, 132; 1988, 131, Glenballythomas 3). (Knox 1911, 221; 1914a, 13; Waddell 1983, 33-5; 1988, 8, No. 23)
This is a National Monument in state ownership: No. 473
