okie here's a lil info on just a few places in Barcelona....
Catedral le Seu-This little 14th century church in the gothic quarter has inside some marvellous gothic stained-glass windows. It is surrounded by 3 squares: Pi Square, Pi Little Square and St. Oriol Square, all of them in a pedestrian area, where on saturdays there is a local market with regional gastromonic products.This cathedral is located in the heart of the Gothic quarter, most of it was built in the 13th and 15th century. The interior is really impressive with a blend of medieval and renaissance styles. There are 29 side chapels inside. The best view of the cathedral is from Placa de la Seu. You can also visit the roof by lift for 2 euros
BARRI GOTICO (Ghotic Quarter) is the old town of Barcelona.Walking by its narrow streets you'll find many interestings things as:Cathedral of Santa Eulalia,the Town Hall, Plaça Reial,and other interesting places to visit,on this picture you can see a view of the small church called Iglesia de Santa Maria del Pí. In this quarter of the city,you can find also some hotels,a lot of small shops,restaurants and cafeterias,is a nice place to explore.
La Pedrera, Casa Battlo, Palau Guell, Parc Guell and of course Sagrada Familia. You can get a pass that gives you discounts if you go to a bunch of these attractions. It can be purchased next door to the Casa Battlo at Casa Amatller. Both are located on Passeig de Gracia. In the summer La Pedrera (also known as Casa Mila) has drinks and Jazz on it's unique rooftop!
La Ramblas -This name comes from the Arabic word for riverbed. It was originally just a path beside a stream that was running through the centre of the old city. Today it is a famous avenue that is the bustling centre of all kinds of activities. You can find almost anything here. Las Ramblas runs from Placa de Catalunya, a main square full of shops, restaurants, and banks, located at the centre of the city, down to the monument of Columbus on the waterfront. The avenue is broken up into five sections, each with its own name and characteristics. The first one is La Rambla de Canaletes, which was named after the fountain Font de les Canaletes. Legends says that whoever drinks from this fountain will forever keep returning to Barcelona. The next area is named after the Estudi General (university) and is called La Rambla dels Estudis. But some also call it La Rambla dels Ocells (avenue of the birds), because of its many places selling birds and small animals. Next is La Rambla de les Flors, where you can buy all kinds of flowers. This is also where you find the century-old Boqueria Market. Inside this market you can find the freshest produce, meat, fish, and dried fruits. Then there is the La Rambla del centre and La Rambla de Santa Monica that brings you to Barcelona’s harbour. At the seafront is La Rambla de Mar where you can find the beach, an aquarium, restaurants, movie theatres and popular nightclubs.
One of the star attractions of Barcelona is the Parc Güell, the second most visited Park after the Ciutadella. Probably only because of its location in the north of the city. The park owes its magnetic attraction to th fact that it was designed by Gaudí. In creating the park, Gaudí used shapes which harmonized with the landscape. Always aware of the struggle betwen man and nature, he built a complex garden of staircases, animalike sculptures, curvy ramps, and viaducts. Today, the park is declared a monument of world interest by UNESCO and has had this status since 1984. Lastly, expect a climb regardless of how you get to the park (well perhaps unless you drive). I think the best way to get there though was with the Bus Turístic.
