Tibidabo

This is the church, that you could see from almost every point of Barcelona. Jesus on top of the church seems to welcome all people with open arms. If you pay few euro, you can get up to his feet.
Go there. Tramvia blau is maybe not worth as you expect from it, neither Tibidabo Funicular,
one of oldest funiculars in Europe. But on the top, you will see the whole city, the surprising part behind the mountains and - I think a big rarity in Christian world - a hundred years old funfair just at the church.

Tibidabo means in Latin: I will give you.
