Ruvo Cathedral (Italian: Concattedrale di Ruvo di Puglia, Concattedrale di Santa Maria Assunta, Duomo di Ruvo di Puglia) is a Roman Catholic cathedral in Ruvo di Puglia, a city in Apulia, southern Italy, dedicated to the Assumption of the Virgin Mary. Formerly the episcopal seat of the Diocese of Ruvo, it is now a co-cathedral in the Diocese of Molfetta-Ruvo-Giovinazzo-Terlizzi. The building is an important example of late Apulian Romanesque architecture, built between the 12th and 13th centuries, with several later alterations.
The current exterior is the result of early 20th-century restoration works which removed the Baroque additions. The church has a sloped façade with three portals: the central and larger one, flanked by two columns standing on lions and surmounted by griphons, has internal reliefs which were once part of an earlier construction. They depict "Christ with the Twelve Apostles", other scenes of the Redeemer's life and plant motifs. The smaller ones, at the sides, have a simpler shape, with two semi-columns supporting ogival arches; they also belonged to previous buildings.
Above the portal is a double mullioned window with a bas-relief of the "Archangel Michael Defeating the Devil", and above it, a 16th-century rose window with twelve radiating columns. This is in turn surmounted by the Sedente ("Sitting One"), an enigmatic figure which has been variously identified as Robert III of Loritello (who funded the construction), while at the top of façade is a statue of the Redeemer. The bell tower, in a different style, most likely formed part of the medieval city's walls.
The interior is divided into a nave and two aisles, ending into three apses, with an orthogonal transept. The nave, like the transept, features a trussed ceiling and, at its sides, has a fake passageway (matroneum) under which are corbels with human, animal or bestial depictions. It stands on two rows of piers, which are each different from another. Some are cruciform, while others are squared; some capitals are sculpted with elements taken from the Christian or medieval mythology, while others feature simpler plant or abstract motifs. The aisles are cross vaulted.
