Salvador Dali (1904 – 1989) once claimed that Perpignan Railway Station was the “Centre of the Universe, because its waiting room is where he got all his best ideas.”

Gaudy or Gaudi? By Henry Shaftoe Antoni Gaudi (1852 – 1926) ranks among the world’s most innovative architects and his masterpiece – the Basilica of the Sagrada Familia, in Barcelona, is arguably Europe’s most spectacular…

I’m assuming you’ve already gasped at the Parc Güell, gazed at Gaudi, stared at the Sagrada Familia, and marvelled at Miró.
For me the charm of Barcelona is to be found in its more homely treasures, on foot or by its efficient public transport system.
