A recent assignment in London took me to Old Broad Street which is home to Tower 42, the second-tallest skyscraper in the City of London and the seventh tallest in Greater London.
The building was originally known as National Westminster Tower and if you are lucky enough to view it directly from above you will see that the tower closely resembles the old NatWest logo. Although as I discovered, if you shoot it from below (which is possible because of the buildings construction) you can see an approximation of the same effect.
The tower was designed by Richard Seifert and formally opened on 11 June 1981 as the tallest building in the United Kingdom (until One Canada Square was completed in 1990).
Tower 42 continued to hold its status as tallest building in the City of London until Heron Tower was opened in 2009.
