Barcelona is a very old city. The first mention in historical records is dated by 3rd century b.c. Since that time a lot of nations left footprint in its heritage: ancient Romans, Visigoths, Moors, Jews and of course Spanish.
It's easier to track Roman footprints in Gothic quarter. Of course there one also can find buildings from Gothic times. The most interesting one is The Cathedral of the Holy Cross and Saint Eulalia (also called Barcelona Cathedral).
Nearby located Kings residence ans chapel. Nowadays these buildings are used for museum of Bacelona history.
It is also possible to find Saint George on streets. The same Saint George is used on Moscow city coat of arms.
A deep inside Gothic quarter there is a corner where a scene from Vicky Cristina Barcelona was filmed. It's a bit hard to do that on your own, I caught it only within free walking tour. I don't want to say I specifically was looking for this place, just it was a part of the tour :)
There were a lot of artists working in Barcelona back in old days: Dali, Picasso, Miro and others. Well, maybe I'm not educated enough, but I didn't get ideas of surrealism and cubism. May be another time.
It was much more interesting to watch photo session on the street. It was cold, but the model was in light dress. That is a hard work (:
Another interesting part of the city is hill Montujik. There is a military museum in the fortress with the same name:
From this point there is available beautiful city view and overview of the city port:
And look at sea-mews:
Or visit museum of art:
However the most interesting thing is Spanish village. Here one can find all types of constructions used in Spain in one mini-village. So one can "travel" through the entire Spain just in one hour.
Another interesting local tradition is to build people towers. The higher is better. World record is about 20 meters high (if I'm not mistaken). Strong men normally are in the lower level normally and on the top normally are small kids, that's why the tradition is often criticised. Despite it looks really dangerous, there was not major incidents.
Spanish people really like football. Here is the biggest stadium in Europe: Camp Nou. It can host up to 100 thousands people for a match though even this is not enough. Official number of Barcelona fan club members is over 200 thousands and everybody is willing to visit classic match (FC Barcelona vs Real Madrid). It's easier with others games, but for a classic one tickets are sold out extremely fast.
So this is the Barcelona.
