The famous Gaudi works in the disharmonious neighborhood were not booked on the internet. We walked from the Bartro House for about 15 minutes. The whole building was very unique. It felt like a layer of waves, strange and beautiful. We bought the ticket elevator to the top floor. Fortunately, we saw the beautiful roof at sunset. Like a desert, smokestacks are solitary soldiers in the desert. I strongly recommend that partners check the sunset time and go to the ticket. One person must take a Chinese interpreter for about 20 Euros. Otherwise, if you look at the other things in vain, there are so many people introducing them, I won't say much about them. OK is worth going anyway.
