Augustus Welby Northmore Pugin (1812–1852) was a key figure in the Gothic Revival movement and one of the most influential architects and designers of 19th-century Britain. Deeply committed to the ideals of medieval architecture, Pugin believed that Gothic was the only true Christian architectural style. He is best known for his work on the interiors of the Palace of Westminster, including the design of the iconic clock tower now known as Big Ben. Pugin also designed churches, furniture, metalwork, and stained glass, all grounded in his belief that beauty should arise from honest construction and craftsmanship rooted in moral and religious values.
