Hospital Sant Antoni Abat
...is the answer to this last Sunday's Challenge. The picture showed part of the original building, recently restored.
The building was originally a convent, built for the order of Carnalite nuns in the 18th century. Later more buildings were added and it converted to a residential hospital.
There is also an emergency department on the side furthest from the original picture, but hopefully you'll never need it during a stay here.
