Mamaia is a popular beach resort on the coast of the Romanian Black Sea.

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.

With half a million people, Nuremberg is Bavaria's second largest city. While its history dates to the 11th century, Nuremberg is most often linked to the 20th century (specifically World War II). It first served as the site of many pre-war Nazi rallies, then was nearly levelled by Allied bombing, then was the site of the famous post-war Nuremberg Trials. The city has much to offer today's visitors, including the rebuilt Nuremberg Castle and the world-famous gingerbread at Hauptmarkt. Hansel and Gretel would have loved this place.

If you’re after a winter sports holiday, you can’t find a more gorgeous place to do it than Interlaken, the popular Swiss resort town.

In summer, hike among the ibex at nearby Neiderhorn, or shop for watches in the town’s boutiques.

Lively Antwerp is a hidden gem. Its medieval streets, Renaissance monuments and vibrant nightlife tend to be overshadowed by its reputation as centre of the diamond trade and as the world's fifth-largest port.

Marvel at the art and architecture of the still unfinished Cathedral of Our Lady, started in 1351.

There's something for everyone in Andorra la Vella, capital of the Principality of Andorra.

Nature lovers can enjoy an urban hike at the Rec del Solà or the Rec del Obac, or be seduced by the Enclar Valley’s remarkable fauna and flora. Need a shopping fix? Peruse the popular Meritxell shopping area.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

Climb the tower of the University's Great St Mary's Church for sweeping views of the city.

Bangkok is full of exquisitely decorated Buddhist temples—as you go from one to the next you’ll be continually blown away by the craftsmanship and elabourate details.
