The whole relief is chiselled in the stone in quite extraordinarily fine detail. The university courtyard is arcaded and provides access to the separate lecture rooms. The Aula, now a museum, has baroque carpets and a painting of Charles IV in the style of Goya. One of the most interesting rooms is the Frater Luis de Léon lecture hall, which is furnished in its original style, with an old dais and primitive wooden desks for the students. The Salinas Music Room has two panel paintings by Juan de Flandes, and the old chapel has works by Fernando Gallego and Felipe Bigarny and a retable by Juan de Flandes. The new chapel has a baroque altar and paintings by Juan de Ribera. There is a fine, wide staircase (with reliefs and stellar vaulting) which leads through to the upper cloisters.

A Gothic door leads through to the old baroque-furnished library, which contains 50,000 old volumes, early printed works, miniature codices and Greek and Latin manuscripts bound in leather and parchment. Nearby is the modern library. Near the entrance to the university is the former Hospital del Estudio, now the Rector’s esidence, which was built in 1600, and the Escuelas Menores, which dates from 1533 and has a Plateresque façade, an arcaded courtyard, and a lecture room containing a huge fresco known as the Ciclo de Salamanca, a hunting picture by Fernando Gallego. There are paintings by Juan de Flandes in the same room.
