Pipe organ of Cathédrale Saint-Nazaire de Béziers, Pipe organ in Cathédrale Saint-Nazaire, Béziers, France

The organ of Cathédrale Saint-Nazaire stands in a Louis XIII carved oak case, its lower section holding three groups of silver-grey metal pipes framed by dark wood, with a taller tier above topped by carved figures and finials. The case rests on carved panels and stone arches. Its restoration lightened the 19th-century chocolate tone back to the blond of the oak.

Guillaume Poncher, a Flemish builder, signed the contract for a new organ on 28 September 1623 under Bishop Thomas II de Bonsi; the instrument and its stone tribune were begun in 1625 and finished in 1633. Jean de Joyeuse repaired it in 1680, and in 1868 the Théodore Puget et fils workshop rebuilt it in Romantic style while keeping old pipework, notably in the positif. The instrumental part has been classified as a monument historique since 11 March 1986.

The organ accompanies church services and concerts held in the cathedral, contributing to the musical life of the place. Visitors can hear it being played during religious celebrations and special performances throughout the year.

The instrument requires specific conditions to preserve its sound and structure, including stable temperature and humidity levels. Visitors should check when concerts or services are being held to hear the organ being played.

The organ is the only surviving example of Flemish organ building from the first half of the 17th century south of the Loire and west of the Rhône. It is counted among the "Seven Organ Wonders of the Hérault", alongside instruments in Montpellier, Saint-Guilhem-le-Désert, Pézenas, Saint-Pons-de-Thomières and Lodève.
