Friday 24 was La Mercè, a big festival in Barcelona. I went to Plaça Sant Jaume to see the castellers. I've always thought this is a beautiful metonymy of the collective work, and I'd say it's not a case that this old tradition had taken deep roots in Catalonia. I've seen castells all my life on tv or films, but this was the first time I had the opportunity of seen them live. Really exciting, at some moments I got goosebumps.
