Kneller Hall is a mansion in Whitton, in the London Borough of Richmond upon Thames which is stone-corniced, casemented and constructed as to its ground floor central range and otherwise built of red bricks, all in the neo-Jacobethan style suitable to 19th and 20th century mansions of its scale. It consists of 17 bays, the central of which is the widest and of stained glass and the two adjacent of which are arrow-slit windows. The bays are split into five recessed or projecting ranges. Two square, pavilion towers form the near left and right bays each tower crowned by a stone and leaded ogee shaped cupola. It takes its name from Sir Godfrey Kneller, court painter to British monarchs from Charles II to George I. Today it houses the Royal Military School of Music, training musicians for the British Army’s 22 military bands, having been acquired by the Army in the mid-19th century. It is also home to the school's Museum of Army Music.
