My tip“45 minutes; about €6. Many steps. On Wednesday mornings it is sometimes free — check.”
A climb to the two towers of the Jesuit Baroque building “La Clerecía” (17th–18th century), opposite the Casa de las Conchas; from the top are the best views of the two cathedrals, the university and the square.
