Grosvenor Square (Left)
"The Georgian period in London coincided very neatly with the Palladian Revival in architecture and art. Lord Burlington, in his 1715 design of Burlington House in Piccadilly, played a major role in popularizing this classical style which became the norm for much of the century. A few years later, in 1725, Lord Burlington was at it again, with his remodeling of Chiswick House, then a country retreat but now part of the greater London sprawl.
At the same time Grosvenor Square was laid out in Mayfair, part of the Grosvenor family's development of that aristocratic district. More London squares followed, notably at Berkeley Square (design by William Kent). Kent was also responsible for building the Treasury Building(1733), and the Horse Guards (1745)."
