 In between his two Grand Tours of Italy (1714 and 1719), young Lord Burlington's taste (the third Earl) was transformed by the publication of Giacomo Leoni's "Palladio" which made him develop a passion for Palladian architecture.In 1717 or 1718, the third Earl began making major modifications to Burlington House and the supervision of the work was undertaken by Gibbs.Later, Colen Campbell was appointed to replace Gibbs, who was working in the Baroque style of Sir Christopher Wren, to recast the work in a new manner on the old foundation.
