I went for an old look with this one. I pass by this building at least a couple of days a week, on my way to/from classes. It had never occurred to me to find out what is in there.
Yesterday I took this picture, and after posting, decided to look it up. It turns out it is now a Clinic (Clínica Creu Blanca), but couldn't find further information about its history.
But still, it is a nice building!
