1978 As you approach the Sheffield Magistrates' Court, a gloomy concrete structure stares you down. B. Warren designed it in 1978, and it makes full use of Brutalism. The roof is composed of thick slabs of glass, which let in light but also expose visitors to the weather. There are no walls within the court building itself, only bare corridors and open rooms. This means that there is no escape from the people inside them when they turn their anger on you. Sheffield Magistrates' Court is one of three courts of its kind in Britain. The others are Leeds City Court and North Yorkshire County Court at Scarborough. Like many other buildings designed by architect Berthold Lubetkin, it stands in stark contrast to the traditional court building which surrounds it. These days it is used as a major public exhibition space called The Cube. Sheffield Magistrates' Court was awarded Grade II* status by English Heritage. This means that it's considered important enough for it to be listed along with other sites such as ancient monuments and buildings constructed before 1750. The reason why English Heritage gave this site this designation is because of its innovative design and how it has influenced later architecture. In addition, the Cube itself now attracts visitors who come to see what is on display within it.
