AN ancient barrow in Purbeck dating back to the late Bronze Age has been added to Historic England's Heritage at Risk Register.
The late Neolithic funeral monument at North Hill, 400 metres north east of Renscombe Farm, Worth Matravers, is one of six new additions on the register for the South West.
It has been included as an archaeological site threatened by arable ploughing.
Portland's Church of All Saints and four other Dorset field monuments, also at risk due to arable ploughing, complete the six new entries.
The bowl barrow at North Hill, thought to have been constructed between 2400-1500BC, has a mound of earth and limestone blocks which is 25metres in diameter and around 0.8metres high.
A Historic England spokesman said: "The barrow lies within an extensive area of field system which is likely to have prehistoric origins.
"However this has been reduced by ploughing to the extent that only fragmented remains will survive."
The register provides a snapshot of the health of England’s most valued historic places, and those most at risk of being lost.
