Day 3. I don't know. I think I walked around and went to a fort. Odds are also good that I ate a bunch of tapas.
Then I descended into a museum under the centre city to look at the fantastic Roman ruins.
So, that's about it for Barcelona. It was indeed an excellent city to visit, with great food, and tons of art to see. I even got to go swimming, which is impressive for October. The people who recommended it were bang on the money.
