Welcome to the London Borough of TOWER HAMLETS in south-east Middlesex
It was incorporated in 1965 by bringing together the Metropolitan Boroughs of Bethnal Green, Poplar and Stepney.
Did you know the so-called Tower of London isn’t in London at all; it’s just outside the City’s bounds and 100% in Middlesex!
