St John's House apparaît pour la première fois dans l'histoire de Warwick au XII siècle. C'était alors un hôpital. Au cours des siècles le bâtiment changea de nombreuses fois de propriétaire, de nom et de statut pour finalement être acheté par la municipalité. Il abrite aujourd'hui le Musée du Warwickshire Regiment. ~~ The history of St. John's House is one of the most complicated but also best documented in Warwick. The first construction on the site was mentioned in the 12th century under the name of Saint John’s Hospital. In 1626, the property was acquired by the Stoughton family which transformed it into a mansion. In the 1660's the building was enlarged to it's present size. At the end of the 18th century it became a private school and at the beginning of the 20th century it was used as a records office by the army. In 1960 the house was bought by the County Council to host the County Museum. Today it is the home of the Royal Warwickshire Regiment Museum.
