There isn’t much I can tell you about Casa Batlló as I have never been there. But Barcelona is very high on my bucket list so I know, eventually, I will go.
The reason why I am posting about Casa Batlló now, is to share this great animated video with you, that I ran across today. I just LOVE it! Please judge for yourself, and let me know what you think. Whether you have been there or not.
My advice is to play the video full screen and maximum sound
