In Bourdon Street is St. Mary's Church, a chapel of ease to St. George's, built for £12,000 by the Duke of Westminster in 1881 to replace St. Mary's Church in Park Street. The building, from designs by Blomfield, is in medieval style. Adjoining is St. George's Workmen's Dwellings Association.

Brook Street was first called Little Brook Street, and afterwards Lower Brook Street. It takes its name from the Tyburn, which flowed down the course of South Molton Lane and Avery Row, by Bruton Mews to the bottom of Hay Hill, and through the gardens of Lansdowne House to Shepherd's Market. It then crossed Piccadilly at Engine Street, and flowed through the Green Park to Buckingham Palace.

Here lived: No. 25 (now 72), Edmund Burke; Sir Henry Holland, 1820-73; 63, Sir William Jenner; 74, Sir William Gull; 57 (now 25), Handel, the composer; Lord Lake, d. 1808; Welbore Ellis, Lord Mendip, d. 1802; Mrs. Delany; 20, Gerald Vandergucht, engraver, and his son Benjamin Vandergucht, painter; Thomas Barker, painter; 25, Rev.

In South Molton Street, on the wall of No. 36, is an inscription: "This is South Molton Street, 1721." At No. 17 lived William Blake, poet and painter, in 1807. The St. George's Schools, at No. 53, were removed in 1889 to Gilbert Street, and the building sold for £2,500.

In Woodstock Street lived: Dr. Johnson, 1737; Prince Talleyrand, 1793; Dr. Parr, 1814. Running out of it are Sedley Place, so named in 1873 instead of Hanover Place, and Blenheim Street, up to 1760 called Pedley Street.

East of New Bond Street, Hanover Square, four acres in extent, was built as a fashionable place of residence in 1716-20. It was to have been called Oxford Square, but the name was changed in honour of the house of Hanover. A few of the old houses still remain, notably Nos. 17 and 23, but most of them have been rebuilt at various times, and are not in any way remarkable. The centre is enclosed and planted with trees, and at the southern end stands a bronze statue of Pitt by Chantrey, erected in 1831 at the cost of £7,000. The principal houses are: No. 3, the offices of the Zoological Society, established in 1826, and removed here in 1846; those of the Anthropological Society; 4, a large handsome building erected in 1774 by Sir George Gallini, and opened by him as the Hanover Square Concert and Ball Rooms. Here J. C. Bach, son of Sebastian Bach, gave concerts from 1785-93. The concerts of Ancient Music and those of the Philharmonic Society also took place here. In 1862 the rooms were redecorated and styled the Queen's Concert Rooms, but were in 1875 disposed of to the Hanover Square Club, established in that year.

No. 10 was formerly the Brunswick Hotel, but has been rebuilt as chambers.

No. 12, formerly the offices of the Royal Agricultural Society, now those of the Shire Horse Society and Kindred Associations.

No. 13, Harewood House, was built by W. Adam for the Duke of Roxburghe, and purchased in 1795 by Lord Harewood, in whose family it remained until 1894, when it was sold to the Royal Agricultural Society, established in 1838 for the improvement of agriculture.
