In Barcelona I got to see lampposts designed by Gaudi but it is Antoni Gaudi's, still unfinished, Sagrada Familia that must been seen and it is well worth paying the Euro 26 to view the breathtaking interior.
My host in Barcelona is far from a fan of Social Media but you may spot his pink shirt in one of the photos below.
I adored my stay in Barcelona. Excellent, reasonably priced, meals out; friendly locals and a walkable place. Hope the photos below encourage you to visit this special Spanish city.
