The Carthusians founded a monastery in 1366/67 in what is called Val Graziosa, a plain overlooked by the Monti Pisani[1] when Francesco Moricotti Prignani was archbishop of Pisa.
[2] This event must have happened not long before Catherine of Siena's visit of 1375, as she mentions in her letters the need to convert the facilities for the Carthusian use.
Fearing a Saracen attack they abandoned the monastery and took up residence at Calci, bringing the records from Gorgona with them, to be duly published at Pisa.
After WW2 members of convents from the Netherlands started to repopulate the building that had been heavily damaged during the war years.
The collection was started in Pisa in the 16th century as a cabinet of curiosities connected to the Giardino dei Semplici.
