Long known for its old-world charm, from the historic Faneuil Hall to the Freedom Trail that celebrates Boston’s preeminent role in the American Revolution, Boston has come a long way towards staking its claim in the 21st century. With the completion of the “Big Dig” that buried Boston’s vast network of highways underground, Boston has hit the new century running. Attractions span beautiful public libraries, fascinating museums and plenty of sports. Boston is destined to grow ever more beautiful as more and more of the ungainly elevated highways are replaced with lush parks.

Bucharest is Europe’s best kept secret. While visually it can't quite compete with other grand Eastern European capitals, it leads the pack in dynamism, energy and forward momentum. The remnants of Communism are still palpable in the urban fabric, but the city has its sights set firmly on the future. Trendy outdoor cafes and high-street shops live side-by-side with gorgeous Orthodox churches and world-class art galleries in the old town, all overlooked by the imposing Palace of Parliament.

Turin, Italy's first capital, is a city awash with history, green parks, and art, not to mention that it is a town with renowned food and even better drinks. Under the arcades of the city centre, there are countless wine bars, grandiose continental cafés, and lively bars and restaurants, all just steps away from luxury shopping streets. Even if it is mostly known abroad for Fiat and Juventus, Turin is a fascinating metropolis with its eyes set firmly on the future, thanks to its young population and great universities.

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.

Manila, the capital of the Philippines, is one of Asia's best-kept secrets. As the capital of the only predominantly Catholic country in the Orient, it presents a unique blend that feels slightly out of place, yet vibrantly infused with Latin American and Caribbean influences. Music and dancing are ubiquitous, and the city's warmth and enthusiasm can easily rival that of Bangkok. Manila's rich history, shaped by centuries under Spanish religious influence and decades of American consumerism, has led to the saying that the city spent "400 years in a convent and 50 in Hollywood".
