Brightwell Castle

Brightwell Castle was in the village of Brightwell-cum-Sotwell, between the towns of Didcot and Wallingford, now in Oxfordshire but until 1974 in Berkshire, in England.

The castle was built in 1145 by King Stephen. At the time there was civil war between himself and his cousin Matilda, whose headquarters were at nearby Wallingford Castle. In 1153 the castle was destroyed by Matilda's son, who later became Henry II.

A manor house now stands on the site.
