Fonthill Abbey — also known as Beckford's Folly — was a large Gothic revival country house built between 1796 and 1813 at Fonthill Gifford in Wiltshire, England, at the direction of William Thomas Beckford and architect James Wyatt. It was built near the site of the Palladian house, later known as Fonthill Splendens, which had been constructed by his father, William Beckford.
