London, the capital of England and the United Kingdom, is a 21st-century city with history stretching back to Roman times. At its centre stand the imposing Houses of Parliament, the iconic ‘Big Ben’ clock tower and Westminster Abbey, site of British monarch coronations. Across the Thames River, the London Eye observation wheel provides panoramic views of the South Bank cultural complex, and the entire city.

Paris, France's capital, is a major European city and a global center for art, fashion, gastronomy and culture. Its 19th-century cityscape is crisscrossed by wide boulevards and the River Seine. Beyond such landmarks as the Eiffel Tower and the 12th-century, Gothic Notre-Dame cathedral, the city is known for its cafe culture and designer boutiques along the Rue du Faubourg Saint-Honoré.

The city of Zurich, a global center for banking and finance, lies at the north end of Lake Zurich in northern Switzerland. The picturesque lanes of the central Altstadt (Old Town), on either side of the Limmat River, reflect its pre-medieval history. Waterfront promenades like the Limmatquai follow the river toward the 17th-century Rathaus (town hall).
