Heron Tower will be a mixture of office and retail space
A new skyscraper has become the tallest building in the City of London.
Still under construction, the Heron Tower has now passed Tower 42, which at 600ft (183m) tall had been the tallest City building for the past 30 years.
Once it is completed in March 2011, the 46-storey Heron Tower, which will also include a restaurant and sky bar, will be 755ft (230m) tall.
Currently, One Canada Square in Canary Wharf in east London is the tallest in the UK, standing at 801ft (244m).
Two other tower giants are also currently being built in the capital.
Bishopsgate Tower will stand at 945ft (288m) when it is finished, but even that will be dwarfed by the Shard London Bridge which is expected to be more than 984ft (300m) tall when it is built.
Both are due for completion in 2012.
Tower 42 was formerly known as the NatWest Tower.
