Casa Batlló is among the most well-known creations of the renowned Antoni Gaudí. Built in 1877, it was redesigned by the famous architect in 1904. Its otherworldly facade, decorated with a colourful mosaic of broken ceramic tiles, has few straight lines. The arched roof looks like the back of a dragon. Casa Batlló attracts thousands of tourists, so come here in the early morning or the late afternoon.

Sangria is far from being your only option in Barcelona bars. Try cava — a popular Catalan sparkling wine. The name originates from the Catalan word for cave or cellar, the traditional storage place for wine. Cava is refreshing and lighter than famous champagne; therefore, it is easier to drink. It goes well with almost any dish. Enjoy the taste of Barcelona!

The Gran Teatre del Liceu was built in 1847. At the time of its construction, it was the largest opera house in Europe. Even today, its concert hall with nearly 2,300 seats on 6 levels looks staggering. The building was reconstructed in the 1990s. The architects preserved as much as possible, adding some state of art technologies. Even if you don’t feel like going to the opera, try visiting the building to see all its splendour.
