A fascinating Benedictine site dating to the Lombard period, the Cripta del Peccato Originale (Crypt of Original Sin) houses well-preserved 8th-century frescoes – depicting vivid scenes from both Old and New Testaments – that have earned it a reputation as the 'Sistine Chapel' of Matera's cave churches. It's 7km south of Matera: all visits must be booked through the website, then joined at the ticket office (at Azienda Agricola Dragone on Contrada Pietrapenta) 30 minutes prior to the scheduled starting time.
