Anstey Castle is a well-documented example of a Norman castle with historical records dating back to the 11th century. Despite partial excavation, the motte and bailey survive well and will retain archaeological and environmental evidence relating to the development of the castle, the landscape in which it was constructed and the economy of its inhabitants.
The monument includes a motte and bailey castle situated at the south end of a broad spur, adjacent to the Norman church of St George's. It survives as a large flat-topped motte which measures 75m north-south by 65m east-west and is c.9m in height. Surrounding the motte is a waterfilled ditch 10m wide with a 5m wide causeway to the south-east. To the north and east of the motte is the L-shaped bailey which is still surrounded on its north-western and north-eastern sides by a dry ditch, 14m wide and 4m deep. Within the projected area of the bailey, just east of the motte, is a square-shaped landscaped mound 22m across and c.3.5m high. It is surrounded by a dry ditch about 8m wide and 3m deep. Its position and shape are incongruous with the bailey and it is considered to be a later ornamental addition. In 1902 excavations carried out by R T Andrews on the eastern edge of the motte summit revealed a trapezoidal foundation of flint dug c.46cm deep into the boulder clay. Fragments of tile and 13th century pottery were also found. The castle is attributed to Eustace, Count of Cologne, who held the manor at Domesday. In 1218 Nicholas de Anstey was ordered to reduce his castle which was in the king's hands in 1225. (Scheduling Report)
