For a city that boasts not only Antoni Gaudí but also a history of Gothic architecture, it's no wonder that Barcelona is a dream for those who love design.
We can thank Gaudí, a prominent player in the Modernism (Catalan Art Nouveau) movement, for some of the most stunning design found in Europe. His creations range from his soaring late-19th-century Sagrada Familia (still unfinished), to Park Güell with its organic swirls and the whimsical Casa Mila and mosiac details.
Futher back, the heart of Barcelona has been the Barri Gòtic, the old city center and with Gothic design galore. Here's where you'll see the elegent Plaça Reial, the soaring columns of the Catedral, and Basilicia de Santa Maria del Mar—whose columns were said to influence La Sagrada Familia.
Spain loves its opera, so it's no wonder that two of its most majestic landmarks are both theaters: Gran Teatre Del Liceu, dating back to the mid 19th century, and Palau de la Musica Catalana, built in the early 20th century.
