Barcelona, Spain

Barcelona is a true global city of breathtaking architecture, countless world-class museums, bustling markets, colorful parks and high-end fashion. This town is big but perfectly discoverable on foot. Imposing Montjuïc Castle is a good starting point for a stunning panorama of the city, and the renowned Joan Miró museum and Catalonian national art museum are also in the area. One might fill an entire day strolling amidst the 12th- and 13th-century architecture of the Gothic Quarter and then checking out the extensive collection of the Museu Picasso. But Barcelona may be most renowned for the unmistakable imprint made on the city by architect Antoní Gaudi, from the spectacular unfinished church of La Sagrada Família to the whimsical Park Güell. More of his work can be found along tree-lined La Rambla, one of the world’s most famous promenades and the perfect place to experience the striking architecture, designer shopping and delicious tapas of the city.
