Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of a round barrow, a burial mound probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated in enclosed disturbed pasture on a slight terrace above the confluence of several streams feeding the River Edw and immediately to the S of Hundred House. The grass-covered barrow is circular on plan and measures about 18.5m in diameter and up to 1.8m in height. It was opened in 1875 and a Bronze Age cinerary urn (a pottery vessel used to contain cremated ashes) is recorded as having been found. The grass-grown vestiges of the 19th-century trenches are still visible.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The well-preserved monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both further burial or ritual deposits and environmental and structural evidence, including a buried prehistoric land surface.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 22m in diameter.
