English: Caledonian Road Underground Station, 6 April 2023. It was built by the Great Northern, Piccadilly & Brompton Railway (GNP&BR) in December 1906 (by then part of the Underground Electric Railways of London, and eventually becoming the Piccadilly Line of the London Passenger Transport Board) and designed by Leslie Green, the UERL’s first Chief Architect from 1902 to 1907, when he became ill with TB, tragically dying in 1908 aged only 33.

Green was an early user of the American steel framed structure so that his two storey station buildings would be able to have offices or flats built on top at a later date – not achieved in all cases, as at Caledonian Road. Green favoured a British Arts & Crafts style and wanted to adopt a corporate style for the UERL. The exterior of his stations therefore featured ox-blood glazed faience tiles and his ticket office green glazed tiles. His platform tunnels all had the name and signage in tiles and featured coloured geometric tile patterns unique to each station.

Caledonian Road is a Grade II listed building. Pictured is the ox-blood tiled frontage.
