I need information about Barcelona, Spain, where I'm going at 28 of June for professional reasons.

In a book I have read about an outdoor market (antiquities, old things, etc.) on Saturday or Sunday. Does anybody know anything about that?

Any other information about where to find antiquities, nice articles for the house, gravures, painting or decorating things is welcome.

During my stay in Barcelona, I'm planning a daily trip to Dali museum, Figueras. How can I go there? I don't prefer to use an organized tour, but to go using public transportation.

Thank you very much for your help. Joanna in sunny Athens
