Which stately home was used during the filming on the British TV series "Brideshead Revisited"?

Castle Howard is a stately home in North Yorkshire, England, within the civil parish of Henderskelfe, located 15 miles (24 km) north of York. It is a private residence and has been the home of the Carlisle branch of the Howard family for more than 300 years. Castle Howard is not a fortified structure, but the term "castle" is sometimes used in the name of an English country house that was built on the site of a former castle.

The house is familiar to television and film audiences as the fictional "Brideshead", both in Granada Television's 1981 adaptation of Evelyn Waugh's "Brideshead Revisited" and in a two-hour 2008 adaptation for cinema. Today, it is part of the Treasure Houses of England group of heritage houses.

"Brideshead Revisited" is a 1981 British television serial starring Jeremy Irons and Anthony Andrews. It was produced by Granada Television for broadcast by the ITV network. Most of the serial was directed by Charles Sturridge, with certain sequences directed by Michael Lindsay-Hogg, who handled the initial phases of the production.

The serial is an adaptation of the novel "Brideshead Revisited" (1945) by Evelyn Waugh. It follows, from the 1920s to the early 1940s, the life and romances of the protagonist Charles Ryder, including his friendship with the Flytes, a family of wealthy English Catholics who live in a palatial mansion called Brideshead Castle.
