looking up in bcn

Walking (my feet off!) in Barcelona gives little opportunity to look up, as there are so many interesting things to look at in every other direction. Although I stopped for a moment a couple of times to explore the tops of tiny courtyards, narrow labyrinth-like streets of the Gothic District, or beautiful architecture of some of the Barcelona's boulevards, like Avinguda Diagonal, about ten-kilometer long artery cutting the city in half.
Also, a little sneak peek of the La Boqueria - the old food market of downtown BCN.
