This university is worth a visit because 1. Established in the 13th century, the University of Coimbra is Portugal's oldest university, and one of the oldest in Europe. Some of the structures date back to Roman times! 2. Harry Potter!! It's not urban legend, J.K. Rowling did spend a few years in Portugal and got some inspiration from the university. if you visit the university, you'll definitely experience some Hogwarts moment.
First, if you are lucky, you'll see the students walking around in black robes. As if they just walk off the film set. Next, visit the gorgeous library. You won't be surprised to see Hermione bent over some books scribbling with a quill.
Now, be warned that visit is not free. You can walk around the ground, but entrance to the library, tower, and other areas require tickets. There are several packages you can choose from, but at the minimal do the "Palace of Schools" which includes the Baroque Library. Also, be warned that there is limited admission to the library, when you buy your ticket they will tell what your time slot will be. They also have guided tours which I'd highly recommend you to reserve ahead of time, by phone or email.
