Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighbourhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travellers say that Istanbul isn’t just one city, but many cities within one.

Copenhagen is one of Europe’s oldest and most popular cities. It’s also one of the cleanest and most metropolitan. The dynamic Danish capital features progressive modern architecture, the must-visit Tivoli Gardens amusement park, stunning palaces, and all the activities and amenities you would expect in a world-class destination. Explore the canals and pretty narrow streets, appreciate beautiful old homes, and find great shopping and people watching on The Ströget.

To the first-time visitor, Palermo is a city of ever-changing character. An abundance of dusty museums, Arabian domes and flourishes of baroque splendor jostle with boisterous markets, chaotic traffic and oppressive summer heat. The Sicilian hotspot is a noisy, polluted, often dangerous, but always fascinating city. Don't miss marvels of Arab-Norman architecture, such as 12th-century Palazzo dei Normanni or San Giovanni degli Eremiti. Ask your hotel to arrange cabs and negotiate fares before setting off.

You view great wine as the essence of a good holiday. Your travel companion, however, is a beer aficionado. Will it be Paris or Munich? Stop arguing and go to Strasbourg, where you can have the best of French and German cuisine, including the booze. The entire central island is a World Heritage Site. Don’t miss the 12th-century cathedral or the storybook "la Petite France" neighbourhood.

Encircled by medieval walls, Canterbury is doused in history. In the Middle Ages, Canterbury’s pilgrimage-site status made it the setting of Chaucer’s seminal "Canterbury Tales," while today, cobbled streets and the 6th-century Canterbury Cathedral secure this city as one of England’s must-visit destinations.

In the "city of dreaming spires", academia takes centre stage. Gaze out at Oxford's world-famous colleges from the top of St Mary's Church tower before heading into the city's pedestrian-friendly streets. The University's Botanic Garden and Ashmolean Museum are Britain's oldest. Follow your nose to the Covered Market for the makings of a picnic to enjoy on a punt or in the University Parks. Mix the historic and modern with visits to the 12th- century village church of Iffley and trendy Cowley's ethnic shops and music venues.
