The Manchester Assize Courts was a building housing law courts on Great Ducie Street in the Strangeways district of Manchester, England. It was 279 ft (85 m) tall and from 1864 to 1877 the tallest building in Manchester. Widely admired, it has been referred to as one of Britain's 'lost buildings'. It was severely damaged by wartime bombing in the Manchester Blitz, and then the remains were demolished in 1957.
