Google Earth Tower 42 and Swiss Re London
The latest building is Tower 42 in London, coupled with a simplified 30 St Mary Axe. Tower 42 is the tallest building in the City of London at 183 metres compared to 179.8 metres for its neighboring 30 St Mary Axe. Built in 1980 by Architects Seifert and Partners, Tower 42 was originally home to the Natwest Bank with rumours that its unique shape mirrored the Natwest's logo at the time. This seems to be however an urban myth, the building is now an office complex with a restaurant on the 42nd floor offering views of London.
