King Arthur King Arthur is a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries AD. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the "Annales Cambriae", the "Historia Brittonum", and the writings of Gildas. Arthur's name also occurs in early poetic sources such as "Y Gododdin".
Old Bailey The Central Criminal Court of England and Wales, commonly known as the Old Bailey from the street on which it stands, is a court in London and one of a number of buildings housing the Crown Court. Part of the present building stands on the site of the medieval Newgate gaol, on a road named Old Bailey that follows the line of the City of London's fortified wall (or "bailey"), which runs from Ludgate Hill to the junction of Newgate Street and Holborn Viaduct. The Old Bailey has been housed in several structures near this location since the 16th century, and its present building dates from 1902.
