A homestead moat southeast of Llangefni on the edge of Malltraeth marsh, enclosing an area of
about 100m. The northwest and southwest sides survive in a fair condition, the others significantly
destroyed. In places the single bank inside the ditch survives to a height of about 2m above the
inside area. Some of the site is covered by 19th century farm buildings. It is the only moated site known on Anglesey. (Evans, 2008) (Evans, Flook & Burnett, 2011)

At Tregarnedd is a moated enclosure of medieval date, the construction of which is traditionally associated with a descendant of Ednyfed Fychan, Gruffydd ap Rhys, in the 14th century, although a recent discussion suggests it may have been Gruffydd's father, Rhys, who was responsible for its construction (Carr 1992). medieval moated sites are rare in North Wales, and no other is known from Anglesey. (Richards and Davidson, 1998).
