Glasgow is the 21st-century magnet of Great Britain, with an energetic yet sophisticated vibe. Formerly Britain's major centre of industrial prowess, it has transformed into a booming hub for art and culture in the past decades. The city prides itself on a never-ending stream of up-and-coming musicians and a thriving nightlife. Glasgow is also home to many excellent modern Scottish restaurants dedicated to preserving their Scottish heritage. Some of the best shopping in the country can be found here, too.

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".

As the capital of the north, Groningen has its fair share of cultural and historical treasures, interwoven by inviting parks and scattered patches of water. This varied landscape is made even more exciting by the student atmosphere, which manifests itself in an exciting bar and café scene.

Lübeck, a UNESCO World Heritage site since 1987, was one of the great mercantile cities in the Middle Ages. The Old Town island, surrounded by the river Trave and the canal, today still communicates the charm of a port. Travemünde is one of the most beautiful sea resorts of Europe which already in 1802 transformed the former fishing- and sailor village into a top address for bathers from near and far. The fascinating sailing Old-timer “Passat”, chugging deep-sea fishing boats and gigantic ferryboats can be admired on the Baltic Sea.

As the birthplace of America, Philadelphia has endured centuries of hardship, obstacles, and triumphs, and remains a top tourist destination in the U.S. Historical buildings, sculptures, and murals line streets that were once walked by the Founding Fathers. While the weather fluctuates between mild springs, hot summers, and chilly winters, the people of Philly can always be seen out and about in the City of Brotherly Love.
