Warwick Castle is a medieval castle developed from a wooden fort, originally built by William the Conqueror during 1068. Warwick is the county town of Warwickshire, England, situated on a meander of the River Avon. The original wooden motte-and-bailey castle was rebuilt in stone during the 12th century. During the Hundred Years War, the facade opposite the town was refortified, resulting in one of the most recognisable examples of 14th-century military architecture. It was used as a stronghold until the early 17th century, when it was granted to Sir Fulke Greville by James I in 1604. Greville converted it to a country house, and it was owned by the Greville family (who became Earls of Warwick in 1759) until 1978, when it was bought by the Tussauds Group.

Warwick Castle is situated in the town of Warwick, on a sandstone bluff at a bend of the River Avon. The river, which runs below the castle on the east side, has eroded the rock the castle stands on, forming a cliff. The river and cliff form natural defences. When construction began in 1068, four houses belonging to the Abbot of Coventry were demolished to provide space. The castle's position made it strategically important in safeguarding the Midlands against rebellion. During the 12th century, King Henry I was suspicious of Roger de Beaumont, 2nd Earl of Warwick. To counter the earl's influence, Henry bestowed Geoffrey de Clinton with a position of power rivalling that of the earl.
