The Certosa di San Giacomo is one of the oldest buildings on Capri. It was built in 1371 at the behest of Count Giacomo Arcucci, Grand Camerario of Queen Giovanna I of Anjou and was initially a convent. The ancient structure of the convent is still visible today in the three blocks that make up the building: one independent and open to all where the pharmacy and the church for women were located; one intended for lay brothers with granaries, stables and laboratories; the last block for cloistered life with the cells around the Great Cloister and the other rooms of monastic life around the Small Cloister.
