Grosvenor Square is the largest (it is about six acres in extent) and, in some respects, the most fashionable of London’s “quadrates.” It was formed in 1695, by that great builder Sir Richard Grosvenor, who employed Kent, the celebrated landscape gardener, to lay out the central enclosure, in which once stood the statue of George I. by Van Nost. It was on this spot that the citizens of London, when setting up those defences against the Royalists, in 1642, on which we found them engaged when we were wandering in the Green Park, erected an earthwork, known as Oliver’s Mound, from which we may probably infer the personal superintendence of the future Protector, or at least his rapidly growing influence. As to-day nearly every house in Grosvenor Square is occupied by some influential or notable individual, so in the past has, practically, each been the home of an interesting personality. The great Earl of Chesterfield was living here in 1733, until he moved to the new mansion he had erected for himself facing the Park, and here it was that Johnson was “repulsed from his doors” or “waited in his outward rooms.” Chesterfield, it will be remembered, married the daughter (she was then termed the niece) of that ill-favoured mistress of George I., Melusina de Schulemberg, created by her royal admirer, Duchess of Kendal, who, by the bye, also resided in the Square. The Marquis of Rockingham, once for a short time Prime Minister, died here in 1782, and Lord North, another Prime Minister, just ten years later, after he had left his former residence in Grosvenor Street, where we have already met with him.
