The triptych above demonstrates the rapid growth of The Shard over the past year. The trio of photographs were taken by Marc-John Photographic from the same spot on the Millennium Bridge on (from left to right) 17th October 2010, 19th June 2011, and 16th October 2011.
As of this month, work has begun on the spire, which will take the building a further 50-odd meters to its 309m summit. The tower is scheduled to be completed next year.
There are plenty more great shots of London over at Marc-John's Flickrstream.
