Hanover Square, London, is a square in Mayfair, London W1, England, situated to the south west of Oxford Circus, the major junction where Oxford Street meets Regent Street. The streets which converge at Hanover Square are [in alphabetical order]: Brook Street, Dering Street, Hanover Street, Harewood Place and Princes Street.
Hanover Square was developed from 1713 as a fashionable residential address by Richard Lumley, 1st Earl of Scarbrough, the soldier and statesman best known for his role in the Glorious Revolution. Like Scarbrough, most of the early residents were staunch supporters of the Hanoverian succession of 1714. ‘Early Hanover Square was decidedly Whig and most decidedly military’, commented the architectural historian Sir John Summerson. Early residents included Generals Earl Cadogan, Sir Charles Wills, Stewart, Evans, Lord Carpenter and John Pepper, ‘names conspicuously associated with episodes in Marlborough’s war and the “Fifteen”.’
