Greater London
The sprawling English capital governing 32 boroughs and the City/Cities & Urban
Greater London covers 1,572 square kilometers along both banks of the River Thames, comprising 32 boroughs plus the City of London. With about 9 million residents, it is Europe's largest city by population within city limits. The London Underground ('the Tube') was the world's first underground railway (1863) and now covers 402 km. London's skyline ranges from the 11th-century Tower of London to the 310 m Shard, reflecting nearly 2,000 years of continuous urban development since Roman Londinium.
