The founding of the World Traders Association movement gave rise to the creation of trading complexes in over 160 cities throughout the world. London was the first in Europe, built in St Katharine Docks beside the Tower of London (though this World Trade Centre closed in 1994). Over 1,000 years earlier the same land was used by the Knighten Guilde to trade in foreign goods, and in 1979 the then Lord Mayor, Sir Peter Gadsden, suggested that this tradition be revived by the creation of the Guild of World Traders to represent members of the international trading community in the City of London.
