Anstey Castle
Anstey Castle was in the village of Anstey, Hertfordshire (grid reference TL404330).
It was a 12th-century stone motte and bailey fortress, founded by Eustace, Count of Boulogne. It passed into the hands of the medieval 'de Anstey' family in the mid-12th century and was strengthened during the Magna Carta war of 1215–16 by Nicholas de Anstey, an opponent of King John. Only the mound motte now remains.
