The first building of the university that is notable for its architecture is the one constructed at the end of the 15th century, after the move of the institution from the Colegiata. It consists of a four sided cloister, which opens up the hallways, and a late Gothic chapel. At the cloister one enters through a portal, also late Gothic, that opens to the Bookshop Street. At the beginning of the 18th century, this became insufficient, prompting an enlargement consisting of a quadrangular cloister with four galleries that open to hallways built at the same time.
