Dear Pavel,
You didn't like "La Rambla?!"

La Rambla is great!
(I think you've got to get out more

).
At least they have a Catholic culture and so there is something to work with with respect to evangelization!
I was in a Carmelite Church that had a chapel to the miraculous Crucifix of Lepanto and I wanted to light a large candle before it.
I fidgeted with the candle, as the flame didn't seem to take.
Then a woman and one or two others came over and started to help me.
Somehow, we finally DID light that candle, by gosh!
They spoke Catalan, so I REALLY didn't know what they were talking about. But they were so very pious and gentle that it really left a deep impression on me.
Ultimately, God will judge who is devoted to Him.
Barcelona and Spain have their history and devotions - we just need to drink deeply of those sacred waters for our spiritual refreshment and health!
Vozdrastviye!
Alex
