Built on the banks of the River Thames, London is one of the world's largest cities. Its many neighbourhood and boroughs are home to an abundance of culture, history, shops and museums. With its expansion and modern development, London's skyline has greatly changed over the past couple of decades, especially in the financial hotspot area of the city. If you don't mind heights, take a trip to the top of the Shard or have a tour on the London Eye. The famous Tate Modern remains contemporary with its excellent lights and if rent a car from London City Airport you can visit the Olympic Park.
