The "Propaganda" or "Collegio di Propaganda Fide" is a catholic building and institution in Rome. It translates as "College of propagation of the Faith". It served as a school to train catholic missionaries from 1662 on.

The building is of particular interest to Swiss bankers since its facade has been designed by Borromini, the Swiss architect who adorned 100 Swiss francs notes for decades.
