Marston Moat is the site of a fortified manor house in the parish of Trudoxhill, Somerset, England. It has been designated as a Scheduled Ancient Monument.[1] It is now on the Heritage at Risk Register due to animal burrowing.[2]
The 23feet wide moat which measures 108feet by 188feet has a 10feet wide and 1feet high bank on its south and east sides.[3] It is situated east of the River Frome.
The site was held by the Bigot family of Marston Bigot before 1195. There is some evidence that they fortified it without a licence to crenellate from Edward II.[4] As a result of this and an insult to the King's messenger Richard Bigot lost his titles to land,[5] which were assigned to William de Meriet and John de Meriet.
It was leased as a farmhouse by the reign of Edward IV however none of the stone remains,[1] and no full excavation has ever been carried out.
