About the event: A new Lord Mayor of the City of London is appointed every year and this public parade is organized to celebrate his inauguration. The Lord Mayor participates in a procession from the City of London to the Royal Courts of Justice in the City of Westminster. As in the Middle Ages, he is accompanied by military displays, marching bands, acrobats, dancers, displays of pomp and charity and symbols of London’s ancient strength and resolve. The annual one-day event attracts about half a million spectators each year and is one of the City’s longest established and best known annual events dating back to 1535. The event starts at 11:00 and the processional route goes from the Mansion House via Bank, St. Paul’s Cathedral and Fleet Street to the Aldwych; the tail of the procession will reach the Royal Courts at about 12.30. There is a short break during the ceremony, then the whole procession sets off again at 13:00 to take the new Lord Mayor back to Mansion House. The procession finally ends at about 14:30 when the last floats reach the City.
