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.

Dubrovnik, in the extreme south of Croatia, is known as the Pearl of the Adriatic. A rich and powerful city state until 1806, the proud city once known as Ragusa has a population of over 120,000.

A wealth of sites lies within the walls of the pedestrian-only Old Town.

The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

Southwest of London is Southampton (Soton to the locals), a metropolitan area centered around the port. However, tucked away on the side streets are ancient gems such as the Tudor House, Mottisfont Abbey, and "God's House," a museum located in a tower in the medieval wall. The ultra-modern Sea City Museum celebrates Southampton's seafaring past and the RMS Titanic. Looking for nightlife? Travelers can dance the hours away with bars, clubs, and live music, all accessible by public transportation.

Distinctive architecture, sun-drenched resorts and eclectic small towns dot Andalusia, a dry, mountainous region of southern Spain that maintains echoes of its Moorish occupation.

Romantics love Granada, home to the Alhambra fortress and an inspiration to the late poet Federico García Lorca. Don't miss a dip in the sea along the Costa del Sol.

The colorful Norwegian city of Bergen is also a gateway to majestic fjords.

Lisbon, the capital city of Portugal, has become an increasingly popular place to visit in recent years, with a warm Mediterranean climate in spite of its place facing the Atlantic Ocean. Full of bleached white limestone buildings and intimate alleyways, Lisbon's mix of traditional architecture and contemporary culture makes it the perfect place for a family holiday. Things to do in Lisbon: As Portugal's capital, there is a lot to see and do in Lisbon. Even exploring the city centre will take a few days out of a family holiday as there is no real central district, although Praça do Comércio is a good central place to start, in Baxia, or Rossio, the city's main square which has a sort of Trafalgar Square feel to it. Or you might try climbing up the Cristo Rei, a huge statue of Christ with spectacular views across the whole city. The Castelo de São Jorge also offers great views and isn't quite such a steep climb. A short tram ride to the west of Lisbon will also bring you to Belem, where you can explore attractions like the Belem Tower and the Belem Cultural Centre, which features a fantastic art collection including works by Dali, Picasso, Warhol and Magritte. In downtown Lisbon, you'll also want to visit the Gulbenkian, which has to be Portugal's answer to the British Museum full of fascinating cultural artifacts and with some superb gardens in the grounds. It's possible to have a fascinating educational family holiday in Lisbon, and there are also plenty of great beaches to work on your tan.
