The monument comprises the remains of a hut platform, probably dating to the late-medieval or post-medieval periods and situated within unenclosed moorland on a gently sloping terrace on the NW-facing slopes of Y Gyrn above Glyn Tarrell. The platform is subrectangular on plan and measures 11m from NW to SE by 6.5m transversely. It is terraced into the slope on its SE end up to a depth of 0.7m; and is terraced out over the slope on its NW end up to a height of 1m. The platform would once have supported a modest building and presumably represents the remains of a seasonal hafotai.

The monument is of national importance for its potential to enhance our knowledge of medieval and post medieval land use, settlement and economy. It is a relatively well preserved example of an upland settlement and retains great archaeological potential to enhance our knowledge of medieval and post medieval stock rearing practices in the upland zone, whether as permanent settlement, regular transhumance, or intermittent opportunistic expansion. The topographical and likely chronological association of the platform with similar monuments nearby (BR391, BR392 and BR393) further increases the importance of the site.

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is rectangular and measures 25m from NW to SE by 20m transversely.
