The site of a Bronze Age barrow which was close to the edge of the road and removed when the road was lowered in the past. 


It appears that there were originally at least two mounds within 30 metres of each other, separated by a road. The second barrow (PRN 0467.00) was partially removed in the 19th century and then levelled by Mr J. Moore in 1886. It measured about 9 metres in diameter and stood up to 1.8 metres high. The mound was composed of loose sand and gravel. 


The roadway is now 12.0 metres from bank to bank with grass covered fields on either side. The lane in which Cronk Aust was situated has been straightened out and resurfaced. No trace of either barrow now exists on the ground.
