It measures ten metres east to west and eight metres north to south, standing just 1.4 metres high, and its entrances are barely large enough to admit a person crouching. One opening on the eastern face is only 0.7 metres wide and 0.5 metres high, and from it two side chambers branch off, the longer of the two running 1.8 metres but partially blocked with limestone slabs. Whether either entrance actually leads into the body of the mound is not entirely clear; the passages may simply terminate, or they may be choked with collapsed material. A second possible entrance in the southwest corner opens to the south and appears to allow access to the interior, though it too may be blocked by collapse.

This is a chambered mound, a type of prehistoric funerary or ritual structure built from drystone walling and stone slabs, sometimes serving as a collective tomb or monument over generations. The mound at Shrone More sits within a wider cluster of prehistoric features: four other chambers lie nearby, the closest just ten metres to the south, others thirty metres to the east. Together they suggest this upland was once a landscape of some significance, used and modified over a long period. The retaining kerb, traces of which survive on the western and northern sides, is a common feature of such structures, helping to hold the mound material in place. Small holes visible on the top of the mound may indicate internal voids, hinting that more survives beneath the peat than is immediately apparent. The site was recorded and described by F. Coyne in a 2006 upland archaeological study covering Mount Brandon and the Paps, published by Kerry County Council in association with Aegis Archaeology.
