The centenary celebrated by the Royal Mint medal issued in 1994 was that for Tower Bridge inaugurated on the 30th of June 1894 by the Prince and Princess of Wales, following a full state procession, in open carriages, through London.

This medal was designed and modelled by numismatic artist Ian Rank-Broadley and illustrates the Bridge from a challenging angle which conveys the dramatic sweep of the suspension cables and the majestic twin towers rising up from the River Thames.

Tower Bridge was constructed primarily of steel, its outer Neo-Gothic stonework was specially designed to harmonise architecturally with the Tower of London. Parliament approved the design in 1885 and work began the following year.
