Castle Rising is a ruined medieval fortification in the village of Castle Rising, Norfolk, England. It was built soon after 1138 by William d'Aubigny II, who had risen through the ranks of the Anglo-Norman nobility to become the Earl of Arundel. With his new wealth, he constructed Castle Rising and its surrounding deer park, a combination of fortress and palatial hunting lodge. It was inherited by William's descendants before passing into the hands of the de Montalt family in 1243. The Montalts later sold the castle to Queen Isabella, who lived there after her fall from power in 1330. Isabella extended the castle buildings and enjoyed a regal lifestyle, entertaining her son, Edward III, on several occasions.
