Tower 42
The City's first skyscraper

Tower 42 is the second-tallest skyscraper in the City of London and the seventh tallest in Greater London. It was designed by R Siefert & Partners and built by John Mowlem & Co from 1971-1980. It held the status of tallest building in the City of London for 30 years, until it was surpassed by the Heron Tower in December 2009. Its shape, seen from above, resembles the logo of its commissioner, the NatWest bank. Architecturally it is of interest for its cantilevered floors around a central concrete core. Other innovative features in the design included double-decked elevators, which provide an express service between the ground/mezzanine levels and the sky lobbies at levels 23 and 24; an internal automated "mail train" used for mail deliveries and document distribution; an automated external window washing system; and computer controlled air conditioning. The tower also had its own telephone exchange in one of the basement levels – this area was decorated with panoramic photographs of the London skyline, creating the illusion of being above ground.Today, the building today is multi-tenanted and comprises office space and restaurant facilities.
