The grind and glam of Nashville, Tennessee was well-earned. After all, it's known nationally and even worldwide as the "Music City." Serving home to the Grand Ole Opry, the Country Music Hall of Fame and many major record labels, Nashville may trace the moniker back to 1874, when a performance by the Fisk Jubilee Singers for Queen Victoria of England earned her instant admiration and statement: "These young people must surely come from a musical city."

Santa Clara will forever be remembered as the site of the last battle of the Cuban Revolution, where Ernesto ‘Che’ Guevara led a group of rebels in a mission to derail an armoured train, resulting in the definitive defeat of the Batista regime. And though bullet holes still bear witness to the hardships of the revolution, today, Santa Clara is a youthful and ferociously creative city, whose large student population contributes to the vibrant nightlife and artistic scenes, and a forward-thinking mentality, making it a unique place in Cuba.

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.

Aarhus lives up to its "smallest big city" motto. It’s petite enough to conquer in a weekend, yet buzzing with enough energy to rival Copenhagen. This is where Danish hygge meets youthful innovation: think Michelin-starred dining alongside quirky food markets, avant-garde architecture framing half-timbered houses, and world-class museums (don’t miss the rainbow panorama at ARoS). By night, craft cocktail bars and live music venues prove size doesn’t dictate ambition.

Beijing's famous Tiananmen Square is vast enough to hold one million people, while the historic Forbidden City boasts thousands of imperial rooms. The city continues to grow with the emergence of ever-higher rising towers, new restaurants, and trendy nightclubs. Despite this rapid development, China's capital has managed to retain its unique charm. The small teahouses in the backyards, traditional fabric shops, old temples, and bustling street restaurants make this city one of a kind.
