Probably built around 1087 on the ruins of an ancient cenobio of Greek-Byzantine origin, by Rodolfo Maccabeo and Emma d'Altavilla (Norman couple), the sanctuary is located on Monte Corno, in the locality of Casale di Pisticci. It was dedicated to the Blessed Virgin Mary and was entrusted to the Benedictine monks of Taranto.

Of apulian Romanesque style, the interior of the church has three naves, ending with semicircular apses. The roof is wooden trusses, supported by pointed arches on square columns.

On the facade stands out the succession of round arches under the frame and particularly important are the large rose window and the portal.
The portal dates back to 1200, has ogival shape, with three bands carved with acanthus leaves with thorns. The inner arch is supported by two lateral columns, with carved capitals, with figures of eagles on the left and tigrotti on the right. The large rose window has the same decorations as the portal and brings light into the church, along with the single lancet windows, on the side walls, equipped with recent stained glass windows, depicting the saints.

The wooden statue of the Virgin, preserved inside the sanctuary, dates back to the 12th century and was crowned by Pope John Paul II on 27 April 1991.
