Grosvenor House

Grosvenor House was one of the largest private townhouses situated on London's exclusive Park Lane in the district of Mayfair. The house was the home of the Grosvenor family (better known as the Dukes of Westminster) for more than a century. Their original London house was on Millbank but, after the family had developed their Mayfair estates, they moved to Park Lane to build a house worthy of their vast wealth, status, and influence in the 19th century.
