Temple Bar is the principal ceremonial entrance to the City of London on its western side from the City of Westminster. It is situated on the historic royal ceremonial route from the Tower of London to the Palace of Westminster, the two chief residences of the mediaeval English monarchs, and from the Palace of Westminster to St Paul's Cathedral. The road east of Temple Bar and within the City is Fleet Street, the road to the west, in Westminster, is The Strand. At Temple Bar the Corporation of the City of London formerly erected a barrier to regulate trade into the City. The 19th century Royal Courts of Justice are located next to it on its north side, having been moved from Westminster Hall. To its south is the Temple Church and the Inner Temple and Middle Temple Inns of Court. As the most important entrance to the City of London from Westminster, it was formerly long the custom for the monarch to halt at Temple Bar before entering the City of London, in order for the Lord Mayor to offer up the Corporation's pearl-encrusted Sword of State as a token of loyalty.
