Evington’s moated site, known locally as Piggy's Hollow, is a substantial earthwork including a former moat and fishponds, lying on the southern edge of the village of Evington, immediately to the west of the parish church, St. Denys. It is the site of a moated manor house that was built by the Grey family of Codnor, Derbyshire, in the 13th century. It also adjoins the northwestern portion of Shady Lane Arboretum, and is an enclosed space with tall wild hedgerows, and mature stands of pines.

The rectangular moat island is approximately 65 metres by 25 metres, with ditches up to 20 metres wide and 3 metres deep on the north, east and south sides. The moat was originally fed by a spring from the north and water is still contained in the northern and eastern arms. On the south western side of the moat, the ditch has been enlarged to form a fishpond 75 metres long with surrounding banks 1 metre high. Two detached fishponds can be found to the west and south.

Piggy's Hollow is one of the best surviving examples of this type of site in Leicestershire. The site has remained undeveloped for many years with no soil disturbance and thus any archaeology is likely to be well preserved.
