The narrow and often steep granite-paved streets of Cagliari’s Castello District are a reminder of a bygone age when the town was dominated at first by Pisans, and later by the Aragonese. Built from white limestone, the walls and towers of the Old Town shimmer in the sun and are a magnificent sight, especially if you are lucky and approach the city from the sea, as the English novelist D.H. Lawrence did in 1921 when he described the Old Town as looking like a "Jerusalem without trees".

The troubled history of Algiers is manifested in its cityscape, architecture and culture. The capital (and the largest city) of Algeria holds impressive monuments and curious surprises for visitors. French and Islamic influences exist next to each other and make it a place as diverse as its people. Visit richly coloured mosques, discover sights and ruins of days gone by, and taste the spicy and delicious food of northern Africa.

In the Alpine foothills, just 50 km from Milan, Bergamo is the most striking city in Lombardy. Built on two levels, the Lower City is more modern and dynamic, whilst the famous ‘Upper City’ boasts a stunning historic centre full of monuments and works of art. In the area around the city the Iseo Lake is well worth a visit, as are the sanctuary at Caravaggio and Crespi d’Adda – the most important company town in Italy, listed as a world heritage site by UNESCO.

Visitors to Reykjavík are thrilled by the pure energy at the heart of Iceland’s capital city: be it from the boiling thermal springs, the natural green energy, or the lively cultural scene and fun-filled nightlife. The world’s northernmost capital is framed by the majestic Mount Esja, which keeps a watchful eye on the city, and the blue waters of Faxaflói Bay. On a sunny day, the mystical Snæfellsjökull glacier appears crystal-like on the western horizon, while mountainous moonscapes spread to the southeast.
