Medieval buildings thrust out of San Nicola's rocky shores, the same pale-sand colour as the barren cliffs. In 1010, Benedictine monks founded the Abbazia e Chiesa di Santa Maria here; for the next 700 years the islands were ruled by a series of abbots who accumulated great wealth.
Although the church retains a weather-worn Renaissance portal and a fine 11th-century floor mosaic, its other treasures have been stolen or destroyed throughout its troubled history, which has seen various religious orders come and go including the Benedictines, the Cistercians and the Lateran Canons. The only exceptions are a painted wooden Byzantine crucifix brought to the island in AD 747 and a black Madonna, probably transported here from Constantinople in the Middle Ages.
