This monastery was built in 1342 by Niccolò Acciaioli and is both artistically and architecturally unique. It was commissioned by the viceroy of the Kingdom of Naples and was originally home to the Carthusian monks. Today Cistercian monks (who have lived here since 1958) give visitors a guided tour of the complex’s treasures. The tour winds its way through the monastery, taking in the Chiostrino dei Monaci e il Capitolo, a cloister featuring Albertinelli’s 1506 work, ‘The Crucifixion’. Other architectural works, completed in different periods, make up the Certosa complex. Free admission.
