Middle Temple is one of the four Inns of Court which have the exclusive right to call students to the Bar. The education and training of advocates lies at the heart of the Inn, but it is also a professional society with a worldwide membership. The Honourable Society of the Middle Temple, to give it its full name, is based on the site of the headquarters of the medieval Knights Templar. Though very little survives from this period - and the area was also extensively bombed in the 1940s - walking through Middle Temple is like walking through history, with links to Magna Carta and the exploration of the New World. Visits inside the Elizabethan Great Hall can be arranged in advance - most of the buildings contain barristers' chambers. Middle Temple is also responsible, with the Inner Temple, for the historic Temple Church.
