Situated on a hill near the town centre, the 15th-century castle was left unfinished after the unpopular Count Tramontano was killed by Matera's townsmen after leaving the cathedral. Didn't he realize bedding every new bride on her wedding night was not going to endear him to the peasants? Four small tiles on Via Riscatto to the left of the cathedral paint a tale of the count's violent death. The castle is currently closed for restoration.
