Twickenham in southwest London, England, is on the River Thames 9.9 miles southwest of Charing Cross, 2 miles southeast of Hounslow, and 2.6 miles northwest of Kingston upon Thames.
Twickenham is the administrative headquarters of the London Borough of Richmond upon Thames.
Historically part of Middlesex, it has formed part of the London Borough of Richmond upon Thames since 1965. The population, including St Margarets and Whitton, was 62,148 at the 2011 census.
Twickenham is the home of the Rugby Football Union, with hundreds of thousands of spectators visiting Twickenham Stadium each year. The historic riverside area has a network of 18th-century buildings and pleasure grounds, many of which have survived intact.
This area has three grand period mansions with public access: York House, Marble Hill and Strawberry Hill House. Another has been lost, that belonging to 18th-century aphoristic poet Alexander Pope. Among these is the Neo-Gothic prototype home of Horace Walpole which has given its name to a whole district, Strawberry Hill, and is linked with the oldest Roman Catholic university in the country, St Mary's University.
