The Royal Courts of Justice are the nation's main civil courts.
Here, the High Court presides over the most serious civil trials in the country including divorce, libel, civil liability and appeals. Criminal cases are handled by the Old Bailey.
The imposing Victorian Gothic building, designed by G E Street, was opened by Queen Victoria in 1882, the architect's finest achievement, and the last major Gothic revival building in London.
Made from 35 million bricks faced with Portland stone, the Royal Courts of Justice are said to contain 1,000 rooms and 3.5 miles of corridors. The stress of building was so great that it caused Street's early death.
The interior of the building is as magnificent as the facade.
The public are admitted to all 88 court rooms and can come and go as they please, although Judges will not suffer interruptions when they are passing judgement or witnesses are taking oaths.
Prominent lists in the central hall indicate which case is being held in which court and how far the proceedings have gone.
The Royal Courts of Justice also contains a small exhibition of legal dress.
