At the northeastern end of Venosa, the abbazia (abbey) was erected above the Roman temple around 1046 by the Benedictines and predates the Norman invasions. Within the complex is a pair of churches, one unfinished. The earlier church contains the tomb of Robert Guiscard, a Norman crusader, and his fearsome half-brother Drogo. The other unfinished church was begun in the 11th century using materials from the neighbouring Roman amphitheatre. A little way south are some Jewish and Christian catacombs.
