Mount Pleasant henge

Mount Pleasant henge is a Neolithic henge enclosure in the English county of Dorset.

Rather like other 'superhenge' sites such as Durrington Walls much of the earthworks have been ploughed or weathered away and it was not rediscovered until Stuart Piggott and his wife Peggy Guido visited the area in 1936. On finding the site they diagnosed it as a henge as its bank was outside its ditch and a later Bronze Age barrow had been placed on top of the bank. The enclosure is egg-shaped, measuring 370 m along its long axis and dates to 2878-2470 cal BC.

A geophysical survey in 1969 identified entrances to the henge enclosure and a smaller inner henge enclosure at the south western end of 45 m diameter. Excavation in the 1960s revealed little material in the henge ditch though some fragments of grooved ware and children's skeletons were found. The inner enclosure however contained large numbers of postholes. The holes were arranged in five concentric rings with a cross-shaped layout of aisles leading into the centre. Within the aisles were further holes interpreted as being for stones. This inner feature was similar to timber circle features at The Sanctuary and Woodhenge.

A narrow, 2 m deep palisade trench was also found running around the inside of the larger henge. Consisting of large oak timbers placed at 50 cm intervals it would have served as a huge barrier to the middle of the site. Evidence that the timber posts that had stood in the trench were burnt was also seen. The...
