1. These three spectacular uprights are of a local brown conglomerate or 'puddingstone'. Alignments of grouped standing stones like them probably date from later Neolithic or early Bronze Age times and their original function is hardly understood. They may have been for ritual, though an astronomical use is not out of the question.

2. Three massive, erect monoliths, aligned 72 degrees E of true N.

Geophysical survey (Hamilton et al. 2002 (AW 42), 105-7), has indicated the presence of medieval or later structures (possibly associated with Trellech borough: nprn 33177) and a c.40m diameter subrectangular ditched enclosure in the vicinity of the stones.

3. The central stone of the three has been dressed to smooth its surface, and bears two large cup marks on its face.
