Church Saint-Vorles, Romanesque church in Châtillon-sur-Seine, France.

Church Saint-Vorles is an early Romanesque church begun under Bishop Brun de Roucy of Langres (980–1016) on a promontory above Châtillon-sur-Seine. Its westwork carries a bell tower rebuilt in the 12th century, and the exterior is banded with Lombard arcatures. The nave has three bays and two side aisles, leading to a double transept and a deep choir with an apse; the north transept arm gives access to the crypt.

A primitive church on this promontory housed the relics of Saint Vorles from 868; the present Romanesque building was erected mainly under Brun de Roucy, bishop of Langres from 980 to 1016, within a castrum. The crossing tower was rebuilt in the 12th century, and in the first quarter of the 17th century the Rosary chapel was added and the crypt enlarged as the Saint-Bernard chapel. In 1023 the relics were carried to the council of Héry.

Vorles was a bishop, not a martyr: born around 530 and died in 591, he was linked to the Burgundian royal house. His relics, kept since 868 in the church, were carried to the Council of Héry in 1023. The canons of Langres ran a school here whose pupils included Saint Bernard around 1090.

The church stands isolated on a promontory above the town, reached from its eastern edge, with the ruins of the dukes' castle and the cemetery on the same plateau. Regular services are no longer held; the building reopens for baptisms and weddings. The crypt, reached by a stair in the north transept arm, holds the 4th-century oratory and the Chapelle Saint-Bernard.

In the north transept arm stands the Entombment of Christ, a 1527 sculpture group from the Renaissance era that is considered a masterpiece of Burgundian carving. The church also keeps a 16th-century diptych showing the transfer of Saint Vorles's relics from Marcenay to Châtillon.
