Coimbra, on the banks of the river Mondego, is famous for its University, the oldest in Portugal has shaped its image to become "the city of students". The old town is dominated by the university which occupies much of the hills above town. It’s easy to see the resemblance to Harry Potter’s Hogwarts. Many of Rowling’s inspiration come from Portugal, where she lived with her first husband.
Upper town is the University. Take to Elevator (if working) or Uber in the morning. Take a few hours to visit all the buildings, then walk down to lower town to the pedestrian only area for the late afternoon.
