This is a large round barrow on the north west edge of Mount Pleasant henge, said to have been added to the henge complex around 1800 bce. It is an impressive size, being not much smaller than the nearby Lanceborough barrow at Maiden castle. Like many local barrows it is now covered in trees , at least this protects it from the plough , sadly Mount Pleasant itself was not spared this fate.
I have included a nearby bowl barrow east of Conquer barrow and Mount Pleasant. This is on a hill overlooking both sites.
