What is recorded here

Grimsbury Castle is a Norman motte-and-bailey earthwork in West Berkshire, built in the decades after 1066 as a centre of baronial authority and local defence. Its mound and bailey still rise from the Eocene clay and silt, marking the kind of rapid military installation the Conquest scattered across England. The castle stopped being maintained after the medieval period, but the ground keeps its shape, waiting for people to imagine the guards, fires and decisions that once turned that soil into a weapon.

The National Heritage List for England records Grimsbury Castle as a scheduled monument. The saved point comes from the centre supplied by the official record. Listing does not by itself mean that the public may enter the place.

Grimsbury Castle was built in the 13th century, likely by the de Montacute family, and later held by the Montagu family, who were prominent in the region during the medieval period. It is important as a well-preserved example of a motte-and-bailey castle and as evidence of feudal military architecture in the English countryside.
