Certosa di San Giacomo is a Carthusian monastery on the island of Capri. Count Giacomo Arcucci, a secretary to Joan I of Naples, established the charterhouse in 1371. He later became a monk himself in 1386. In 1553 the monastery was restored and fortified and a tower was erected which collapsed in the 18th century.
There was often conflict between the islanders and the monks, who owned land as well as grazing and hunting rights. During the 1656 plague in Capri, the monks sealed themselves off, whereupon the islanders threw their corpses over the wall of the monastery in retribution.
Since 1974 the charterhouse houses the Karl Wilhelm Diefenbach museum among others and is used for cultural events. A high school is also on the premises.
The charterhouse has three main areas: the pharmacy and women's church, the buildings for monks, and those for guests. The cloister (Chiostro Grande) is of a late Renaissance design, while the Chiostro Piccolo features Roman marble columns.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
