With glass skyscrapers that reflect the bustle of daily life, magnificent buildings such as the Emirates Palace, its lively souqs, excellent restaurants and long stretches of white beaches lapped by the crystal clear waters of the Gulf, Abu Dhabi is a city of outstanding contrasts.

Speaking of Parma, the first things that come to mind are probably the ham and Parmesan cheese. Indeed, Parma is one of the most important culinary centres of Italy — but this city is so much more than that. Parma was the capital of a very powerful duchy, which left a legacy of stunning monuments and palaces. In addition, the splendour of that period created fertile grounds for the flourishing of art. In fact, Parma became one of the main centres for opera, thanks to its amazing theatres and its fine citizen Giuseppe Verdi.

Kerala’s first city, with its knotty official name of Thiruvananthapuram (often substituted by the shorter, more manageable Trivandrum), is a rich introduction to southern India's urban and cultural life. Trivandrum tends to be unjustly overlooked en route to the state's beachside settlements but easily warrants a few days of its own.

Brussels, a city that continues to surprise and move you. This city-region capital of 500 million Europeans is waiting to share its treasures with you. It’s a fair bet that its stormy history is the reason for its open-mindedness, warmth and friendliness. You’ll feel right at home in Brussels. As well as its historic monuments, Brussels has so much to share with you: its comic strip speech bubbles, its Art Nouveau façades, the talent of its stylists and designers, its delicacies and its surrealism, which can be found on every street corner.

Walking through Xi'an is like stepping back in time. The towering ancient city walls, the quiet streets around the Drum and Bell Towers, and the bustling markets all carry a sense of history. You can almost hear the whispers of ancient merchants who walked the Silk Road or feel the presence of emperors who once ruled here. Xi'an is a place where the past and present exist side by side in a way that feels both natural and humbling.
