Vienna has a long memory. Once the capital of the Habsburg Empire, the city still carries signs of its imperial past in its palaces, concert halls, and wide boulevards. Visitors can walk through the Hofburg complex, where emperors once ruled, or tour the opulent rooms of Schönbrunn Palace, which features 1,441 rooms and a maze in its gardens. But Vienna’s many historic buildings now house contemporary art museums, cafés, and institutions that reflect the city’s modern identity.

Denver, Colorado, known as the “Mile High City” for its elevation exactly 5,280 feet above sea level, offers far more than a mountain backdrop.

While the nearby Rocky Mountains are visible from almost anywhere in the city, places like City Park and Washington Park offer wide green spaces right in town.

Santa Fe, New Mexico, with its adobe-style architecture, vibrant arts scene, and unique blend of Native American, Spanish, and Anglo influences, is a destination like no other.

Nestled in the heart of Sri Lanka’s hill country, Kandy is a city steeped in history, culture, and natural beauty.

Willemstad, the capital of Curaçao, is unlike any other city in the Caribbean.
