Friday or Saturday?

John... what is "Gaudi world"??

Segrada Familia, Batlló, Sant Pau Hospital, Block of Discord, etc. Just was wanting to avoid listing all the Moderisme possibilities in Barcelona.😀

Montserrat is somewhat weather-dependent. Sant Pau involves a little walking around outdoors. You need to get from building to building, and it will be easier to appreciate the building exteriors if you aren't being rained on. The other sights you mentioned are more interior-focused (assuming you plan to go inside Casa Batllo). I'd hope to retain some scheduling flexibility, at least for Montserrat.

My impression is that the Gaudi sights are always full - the crowds are about the same always, since there are limited quantities of tickets.

aaah yes......weather can be the great equalizer 😀. Book your tickets....keep the faith.....have a Plan B ready.

Perhaps because it was not designed by Gaudi, Sant Pau is--so far--blessedly uncrowded.

I was asking on purpose because Gaudí is just "one" of the Modernist architects -the most popular, I grant you that, but by no means the only one. You have a large number of Modernist places worthwhile seeing in Barcelona, many of which are not from Gaudí. I thought you might want to realise that. Furthermore, Hospital de Sant Pau, for example, is not from Gaudí but from Domènech i Montaner. I would raise this point to anyone visiting the city, or other parts of Catalonia for that matter as Modernisme is a cultural art and architectural movement that, in the Iberian Peninsula, happened in Catalonia but not in Spain hence you won't find it elsewhere. Modernisme shares many similarities with the Art Nouveau movement in Central Europe. Anyhow, aside Gaudí's sites -which btw, there are over a dozen of them worth visiting- there are a number of visitable sites by architects like Sagnier, Domènech i Montaner, Puig i Cadafalch, Pupurull, etc that are a must for any Modernist lover. :)

To add to what my amigo Enric has written, I took the TI's Moderisme tour which was an eye-opener. The guide pointed out so many bits of Moderisme that I had walked past without seeing, but after the tour I learned to look for them - they are everywhere!! My favorite place in the Palau de la Musica, by Domènech i Montaner. Actually my absolute favorite is a home he designed on the "Block of Discord" but when I was last in Barcelona (wow - 2 years ago) it was closed to visitors.

Wow, 2 years already?... girl, time flies, doesn't it? Ad me’ah ve’esrim shanah!

Thanks Enric! Great information again!!!! Yep, I do know that Gaudi is not the only Modernisme architect and contributor to Barcelona's scene. I do need to dig a little further into what works well for that Friday. Looks like that will be my big day to invest into the Modernist architecture......except for the Palace of Catalonia Music (Thursday afternoon) and Park Guell (Monday morning). Guess I am going to have to flip a coin (Euro) on whether I pay admission to Casa Batilo or Casa Mila? Segrada Familia will start my day.
