London, United Kingdom

An unmissable landmark of London is the Palace of Westminster which houses the Parliament of the United Kingdom and is the 'heart of British politics'. The site includes St Margaret's Church and the notable religious building, the Westminster Abbey, which is the traditional place of coronation and the burial site for English and British monarchs. The fourth World Heritage Site to check out on your London tour is the historic settlement of Greenwich which encompasses the Royal Observatory Greenwich, marking the Prime Meridian, 0° longitude, and GMT.

Other famous sights of London that should be mentioned are the Buckingham Palace (the residence and administrative headquarters of the reigning monarch of the United Kingdom), the London Eye Ferris wheel, Piccadilly Circus, St Paul's Cathedral, Tower Bridge - an iconic symbol of London, Trafalgar Square, and the modern symbol of the city - The Shard.

What is more, the London metro (called the "Underground" by locals) is the oldest railway network ever to be built underground in the world. Topping that, London is also home to many top-notch museums, galleries, libraries, sporting events, and other cultural institutions. Among the highlights are the British Museum, the National Gallery, the Natural History Museum, the Tate Modern, the British Library and the West End theatres.

When visiting London make sure to take a ride on the red double-deckers and make a call on from one of the iconic red telephone booths, and treat yourself to an authentic English breakfast with eggs and bacon.
