For five years, I was lucky enough to study law at one of the oldest universities in Spain. And not just one of the oldest, but also in my opinion one of the most beautiful. When you spend your days having to memorize laws, articles, etc, it's far more enjoyable to do it in wide corridors covered with mosaics, and a beautiful inner courtyard with benches to sit on and chat. A large part of the building was renovated a few years ago, adding a new wing and dividing some of the old, big classrooms into smaller ones. There are stained glass windows alluding to the themes of law and justice. The classrooms are simple but functional, and the library is always full of students. Worth a visit to see a fascinating historical building if you're passing through the area.
