London the capital of England's skyline is not as full of tall buildings as many other citys around the globe due to restrictions on building heights. These are to protect views of certain buildings from other locations in the capital including St Pauls Catherdral.
Up until the early 1960's building heights in London were limited to just 100 feet (30 metres), although as with many rules there were some exceptions to this rule. The primary reaosn for this rule was to make every floor of a building accessable to the fire brigades ladders.

30 St Mary Axe, The Gherkin, Swiss Tower - Whatever name you choose to call it this building has a unique design and looks at home in the london skyline.
One Canada Square - Known to many as the Canary Wharf Tower this building has been the tallest building in England for many years taking over from Tower 42, and will soon be taken over by the new arrival of buildings to sculpt the London skyline.
London Shard Bridge - Again due for completion around 2010 this building will be take over and become the tallest building in London and Europe.
The structure does look like a large shard of glass.
Tower 42 (formely Natwest Tower) - Was the tallest skyscraper in London for over ten years until the arrival of the 1 Canada sqaure Canary Wharf development. This building still dominates the City of London skyline and is still best known by its original name.
