Augustus Welby Northmore Pugin (1 March 1812 - 14 September 1852) was an English architect, designer, artist, and critic who is principally remembered for his pioneering role in the Gothic Revival style of architecture. His work culminated in designing the interior of the Palace of Westminster in Westminster, London, England and its iconic clock tower, later renamed the Elizabeth Tower, which houses the bell known as Big Ben. Pugin designed many churches in England and some in Ireland and Australia. He was the son of Auguste Pugin, and the father of Edward Welby and Peter Paul Pugin, who continued his architectural firm as Pugin & Pugin. He also created Alton Castle in Alton.
