The great organ that is in the gallery at the end of the nave, above the west portal, is an instrument built between 1736 and 1740 by Christophe Moucherel, already famous at the time for a similar masterpiece achieved at the Cathedral of Saint Cecilia of Albi, recently completed.
From 2001 to 2005, Jean Daldosso de Gimont (Gers), did an outstanding restoration work of the instrumental part and the sideboard, which regained its original polychromy. The mechanics, the bellow, and the plumbing were entirely restored in their state in 1875.
As a result, the Saint Vincent Church regained an exceptional organ, by both its sounds and its historical value.
