The London Underground is a metro system serving a large part of Greater London and parts of Buckinghamshire, Hertfordshire and Essex. Seventy-one of the 272 London Underground stations use buildings that are on the Statutory List of Buildings of Special Architectural or Historic Interest, and five have entrances in listed buildings.^[1] Buildings are given one of three grades: Grade I for buildings of exceptional interest, Grade II* for particularly important buildings of more than special interest and Grade II for buildings that are of special interest.^[2]

The Metropolitan Railway's original seven stations were inspired by Italianate designs, with platforms lit by daylight from above and by gas lights in large glass globes,^[3] and the early District Railway stations were similar; on both railways the further from central London the station the simpler the construction.^[4] The City & South London Railway's architect Thomas Phillips Figgis designed red-brick buildings topped with a lead-covered dome containing the lift mechanism, such as the Grade II listed station at Kennington.^[5][6] The Central London Railway appointed Harry Bell Measures as architect, who designed its pinkish-brown steel-framed buildings with larger entrances.^[7] In the first decade of the 20th century Leslie Green established a house style for the tube stations built by the UERL, which were clad in ox-blood faience blocks;^[8] eleven of these stations are listed.^[9] Harry W. Ford was responsible for the design of at least 17 UERL and District Railway stations, including the listed Barons Court.^[10][11] The Met's architect Charles W Clark had used a neo-classical design for rebuilding Baker Street and Paddington Praed Street stations before World War I and, although the fashion had changed, continued with Farringdon in 1923.^[7] In the 1920s and 1930s, Charles Holden designed a series of modernist and art-deco stations, some of which he described as his "brick boxes with concrete lids",^[12] many of which are listed, five at Grade II*. Holden's design for the Underground's headquarters building at 55 Broadway including avant-garde sculptures by Jacob Epstein, Eric Gill and Henry Moore,^[13] incorporates St James Park station and is listed Grade I.^[14]
