Augustus Northmore Welby Pugin is far from being a household name, yet he designed the iconic clock tower of Big Ben as well as much of the Palace of Westminster. The 19th-century Gothic revival that Pugin inspired, with its medieval influences and soaring church spires, established an image of Britain which still defines the nation. Richard Taylor charts Pugin's extraordinary life story and discovers how his work continues to influence Britain today.
