The building adjacent to the church is the famous Dubrovnik college Collegium Ragusinum. The Jesuits came to Dubrovnik in the first half of the 16th century aiming to open a Jesuit College, which they accomplished as late as 1658. After the Jesuit Order had been abolished in 1773, the Collegium was taken over by the Piarists.
The building now houses a classical grammar school. The old library includes over 10,000 volumes with valuable incunabula and manuscripts by Dubrovnik writers.
