Warwick Castle was built by William the Conqueror in 1068 on a bend of the River Avon. Since its construction in the 11th century, the castle has undergone structural changes with additions of towers and redesigned residential buildings. Originally a wooden structure, it was rebuilt in stone in the 12th century. During the Hundred Years War, the facade opposite the town was refortified, resulting in one of the most recognizable 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, who converted it to a country house. It was owned by the Greville family until 1978 when it was bought by a leisure company.
