One of the most important monuments in Matera, the monastic complex of Madonna delle Virtù and San Nicola dei Greci is composed of dozens of caves spread over two floors. The church of the Madonna delle Virtù was built in the 10th or 11th century and restored in the 17th century.
Above it, the simple church of San Nicola dei Greci is rich in frescoes. The complex was used in 1213 by Benedictine monks of Palestinian origin. From late June to October a modern art exhibition is showcased in Madonna delle Virtù.
