Mount Pleasant henge is one of the large Wessex henges and lies about a mile east of Dorchester. The bank was originally about four metres high surrounding an egg-shaped enclosure about 370 metres along its longer axis and about 320 metres along the shorter one. Originally the 4.8 hectare area could be accessed by four entrances. The bank is outside the ditch which had a diameter of about 43 metres with a single entrance.
