Visited in May 2025. These two works by the Catalan architect Lluís Domènech i Montaner are both excellent locations to visit, and as other reviewers have said, are just as good as the Antoni Gaudí works.

Sadly, due to how full our trip already was my wife and I did not have the time & energy to do the full tours of both of these locations, but we did make sure to at least walk inside of them to look around. The hospital in particular photos very well from the outside. Both locations are really not difficult to access via public transportation, simply buy a day pass that will give you 10-swipe access to all of the Metro stations in the city. If you're going to do the tours of these in addition to tours of the Gaudí buildings (not to mention anything else within Barcelona, I highly recommend giving yourself at minimum four days, or be confident that your stamina for audio guided tours will not flag if you really want to marathon them in a shorter amount of time.

Everything can be accessed in English if you don't speak Catalan. In fact, because of how tourist-focused Barcelona is, you will most likely see and hear more English & Catalan than you will Spanish during your time in the city, so don't be worried about missing out on details in any of the tours or having a confusing time getting around.
