London (Greenwich), England, United Kingdom

One of the world’s great cities, London seamlessly blends history and modernity in its iconic landmarks and rich culture. After watching the Changing of the Guard at Buckingham Palace, walk through the historic streets of Westminster to see the majestic Houses of Parliament and Big Ben, and then get a view of it all from high over the Thames on Europe’s tallest Ferris wheel, the London Eye. UNESCO World Heritage sites abound, from Westminster Abbey and the Tower of London to the Royal Observatory of Greenwich. Art and history buffs will discover some of the world’s finest paintings, sculptures and artifacts in the collections of the British Museum, National Gallery and Tate Modern. An equally enjoyable day could be spent exploring the markets of Camden and Notting Hill, the galleries and cafés of Shoreditch, or the upscale boutiques of Mayfair, as each neighborhood reveals a distinct personality in its shops, restaurants and street life.
