Barcelona is the most visited city in Spain and undoubtedly well known internationally thanks to its history, cosmopolitan society and the Basílica La Sagrada Familia, designed by Gaudí and meant to be his most internationally famous work. The church includes two main architectural styles: Gothic and Spanish Modernism which, finally, led to the “style of Gaudí”. The construction of the Basilica began in 1882 and remains still incomplete.

Another interesting place designed by Gaudí is Parc Guell, opened in 1926. It is located north of Barcelona, in the Mount Carmel, which allows visitors to have a special sight of the city. Access to the park can be reached by public transport.
Back at downtown you can stroll down Las Ramblas, the most famous and populous avenue in Barcelona. Throughout the whole street, you can enjoy all kinds of street art or turn west side of Las Ramblas and reach Barrio del Raval, certainly the most cosmopolitan part of the city. This area includes other attractions like the Museum of Contemporary Art, Church of St. Augustine or the Boqueria market, where you can buy and enjoy fresh food and delicacies.
Barcelona has one the biggest aquariums in Spain, located at the harbor of the city. Its facilities are big enough to home more than 11,000 animals. Also you can take a walk along the port and have a drink or eat in one its restaurants.
Like the Sagrada Familia, the Barrio Gótico is one of the essential places when visiting Barcelona. Its history begins with the romans, more than 2,000 years ago, although there have been many changes along centuries. Still, this place makes visitors feel like in the middle ages.
Barcelona, of course, has many other places worth visiting, like Picasso Museum, Basilica Santa Maria del Mar and so many more.
