This church was run by the order of St Augustine. It was founded in the thirteenth century by Charles I of Angevin, and nicknamed 'alla Zecca' (or, 'at the Mint'), because it was located very close to the building which housed the mint. It is situated on the foundations of an ancient Roman fort. A staircase with an eighteenth century bannister made from volcanic rock leads to the entrance of the church which stands above street-level. The façade and the bell were both designed in the second half of the seventeenth century by Bartolomeo Picchiatti, who placed great emphasis on color. Following the earthquake of 1980, the church was closed due to the considerable damage it had incurred. Instead, it became possible to visit certain parts of the nearby convent (the entrance of which is at No. 174 Corso Umberto I): the elegant main cloister built in the seventeenth century, the Gothic 'Sala Capitolare' complete with cross-vaults and illustrated capitals.
