Places to See In Barcelona, Spain

Gaudi architecture, including the Parc Güell, the still unfinished Sagrada Família and the houses; La Pedrera/Casa Milà and La Casa Batlló. Park Güell. This is on a hill overlooking Barcelona, so expect a relatively steep walk to the top (Lesseps metro station, then follow arrows which are met every 300 m); you will be rewarded with a panoramic view of the whole city. The park has two distinct parts, a relatively undeveloped natural area near the top of the hill, and the more famous (and crowded) sculpture park below. The sculpture portion is full of walkways and other structures exhibiting the distinct and colorful style of Gaudi, including the famous terrace. Free entrance. La Pedrera - entrance (Diagonal metro station) costs approximately 8 Euro.

Sagrada Família - To get up to the tower by elevator costs 2 Euro (long queues). Previously, it was possible to go up the spiral stairs, but now they only allow you to get back down. The most impressive thing is to see Sagrada Família at night with lights on, this is the time when you understands why people say that it is built of bones. Entrance costs 9 Euro. Sagrada Família metro station.
The ruta del Modernisme (details avaiable from the tourist offices) takes you round all the best Modernisme (art nouveau) buildings in Barcelona. The full pack also includes discounted tickets to many attractions such as La Pedrera and Casa Battlo.

La Rambla, the most famous boulevard in Barcelona.
Plaça d'Espanya with famouse red colums built before Olympic games and musical (in summer) fountain.
The Gothic Quarter , with the Cathedral of Santa Eulàlia and the Gothic Church of Santa Maria del Pi. Also worth the visit is the Gothic Basilica of Santa Maria del Mar, near the Picasso Museum.
San Pau del Camp is a romanesque church - one of only a few in Barcelona - with a fine cloister which feels almost Arabic in style. A little island of calm in a very busy city.
La Plaça Reial is located next to La Rambla and is considered to be one of the most beautiful
squares in the world. Also look at the Gaudi streetlights!

Olympic stadium and village on Montjuïc hill, including the Montjuic Castle with his beautiful sightseeing.
Tibidabo is located on the mountains of Barcelona and offers a spectacular view of the city (532 m high). This is a place where according some legends the Devil seduced Jesus Christ offering him whole world in exchange for his worship. There is a wonderful church over there. To get there by yourself you need to take metro till Av. Tibidabo Station, then Tramvia Blau, and then Funicular up to the mountain. It reduces the time you spend for getting there. If you have the whole day after leaving the metro you can walk up to the view point.
Olympic Port. It has a large number of restaurants, bars and other establishments which have made Barcelona's nightlife even more intense.

FC Barcelona. If you're a football freak then you can't miss a visit to Camp Nou, the home ground for Barcelona's biggest and most popular team, and one of Europes greatest footballing 'cathedrals'. FCB are the only major football club in the world that doesn't sell advertising space on it's strip, and this is because the club is about more than just making money. During the Franco era, FCB were the only way that supressed Catalans could vent their anger against his dictatorship, and because of this it became a symbol of Catalan identity. Camp Nou is the biggest stadium in Europe with a capacity of 98,600 people, and it also has shops and a museum of the club's history. Match tickets are relatively cheap (25-35 Euros) and games hardly ever completely sell out, unless it's a match against the hated rivals Real Madrid, or one of the other top teams (currently Valencia or Deportivo la Coruna.) With the quality in the current team, there's always a few goals, and it's nearly always a resounding win for Barca! Stadium tours aren't fantastic, but for a quick recent history of matches played there, consult the backs of the doors in the cubicles - most have alot of graffiti championing their team that played here!

Zoo-Barcelona It is located in Parc de la Ciudadella. Prior to his death, this zoo was famous for its albino gorilla "Snowflake". Today this zoo still has many other features including a science museum inside the zoo.
Poble Espanyol. A fake village with replicas of characteristic buildings in Spain (like the Avila walls, the Vall-de-roures town hall, etc). The village hosts the Fondation Fran Daurel, where you can enjoy an intresting Modern Art collection boasting Miró, Picasso, Tapiès and other, mostly Spanish and Catalan, nowaday's artists. The audio tour is very worthwhile here.
Palau de la Música Catalana Modernist design by Lluís Domènech i Montaner is in the UNESCO World Heritage since 1997, a masterpiece of Catalan's Modernist Architecture.
Palau Nacional with its art gallery
Monestir de Pedralbes A beautiful Gothic monastery near the university. There is a picture gallery, a museum which depicts the monastery life, a church and a marvelous chapel covered with medievil frescoes.

The Museum de l'Eròtica de Barcelona on La Rambla, just in front of the market IS a huge tourist trap (for the more open Western cultured tourist). For the more conservative Asian folks, this can be an eye opener. The tour isn't worth it, unless you wish to see (or never seen) old paints of kamasutra. The only interest is the huge phallus in the hallway, makes funny pictures!
