Built in 2004, Barcelona's third tallest building standing 144 metres (474 ft) high, the Torre Agbar quickly became a symbol of the city due to it's shape and stand out illuminations. Covered in LED lights that allow for any number of combinations and patterns to be shown on the facade, visitors will usually find it lit up blue and red, the colours of the city.
13. Torre Agbar
The literal meaning is 'Spanish Town'. Built in 1929 as an exhibit for the architecture and culture of Spain, it houses 117 buildings representing fifteen autonomous regions of the country.
12. Poble Espanyol
The Columbus Monument is a 60 metre (197 ft) tall monument built in 1888 to honour Christopher Columbus after his first voyage to the Americas. Visitors can find it easily at the southern end of La Rambla, the most touristy street in the city.
11. Monumento A Colón
Created in 1877, The Citadel Park consists of 70 acres of tranquil greenery. Within the grounds you'll find the city zoo, the Parliament of Catalonia, a small lake, the Mamut statue and the Cascada fountain.
10. Parc De La Ciutadella
Built in a similar style to arches found in Paris, London and New York, this is Barcelona's Triumphal Arch. Built in 1888 for the Barcelona World Fair, it stands at 30 metres (98 ft) tall, carved from red brick.
9. Arc De Triomf
One of the cities biggest squares can be found at the foot of the Montjuic Hill. Built for the 1929 International Exhibition it is now essentially a giant roundabout with a fountain in the middle. Still a rather brilliant sight with the long straight roads leading to it, columned arches surrounding and the two 47 metre (154 ft) high Venetian Towers leading up to the art museum.
8. Plaça d'Espanya
As with Plaça d'Espanya above, the National Palace was also built for the 1929 International Exhibition. Since 1934 this Spanish Renaissance inspired building has been home to the National Art Museum of Catalonia. This wonderful looking domed symmetrical building sits high up on the Montjuïc hill, allowing for great views over the city.
7. Palau Nacional
Completed in 1912 this modernist building is the last piece of civil work designed by Antoni Gaudi, having hailed from Barcelona he became one of the most distinctive and celebrated architects in history. The Casa Mila is a UNESCO World Heritage Site.
6. Casa Milà
Built in 1900, the Casa Amatller is one of the three most important buildings in the famous Illa de la Discòrdia (Block of Discord).
Another of the most important buildings in Barcelona is the Casa Batllo which stands to the right of the Casa Amatller. Built in 1904 it is one of Antoni Gaudi's masterpieces, with it's oval windows, flowing stonework and colourful mosaic facade it truly is a work of art.
5. Casa Amatller & Casa Batlló
Built in 1339 is the Cathedral of The Holy Cross And Saint Eulalia, otherwise simply known as Barcelona Cathedral. This beautiful Gothic cathedral with it's ornate and detailed facade can be found in the ever popular Gothic quarter of the city.
4. Catedral De La Santa Cruz y Santa Eulalia
Opened as a park in 1926, the Park Guell is another work of art by Antoni Gaudi. The park is filled with flamboyant buildings and mosaic pieces. The focal point is the terraced area surrounded by a long bench in the shape of a serpent, and the high point of the park provides one of the best views of the city. The Park Guell is a UNESCO World Heritage Site.
3. Park Güell
At the summit of Mount Tibidabo is the Expiatory Church of The Sacred Heart of Jesus. Work began on this wonderful looking building with it's enormous Jesus statue on top in 1902 and took 59 years to complete. They say location is everything, and this church has an amazing spot atop a mountain allowing for incredible views across the city and coast.
Just below the church is the Tibidabo Amusement Park. It opened in 1905 and is the third oldest amusement park still running today.
2. Temple Expiatori Del Sagrat Cor
Designed by Antoni Gaudi, The Basilica And Expiatori Church of The Holy Family is known worldwide as simply, 'The Sagrada Familia'.
Building began in 1882 and it is hoped that it will be completed by 2026. Upon completion the spire will have a height of 170 metres (560 ft), making it the tallest church in the world. It is intentionally 1 metre shorter than the Montjuic Hill as Gaudi believed his creation should not surpass Gods.
One of the most iconic and unique buildings on Earth, it is a national monument, a UNESCO World Heritage Site, and it also made the final shortlist for one of the wonders of the world. It is indeed a work of art.
