Listed as a historical monument in 1979. The first stone of what is now the Basilica of Notre-Dame la Daurade was laid in 1764. It was built on the site of an important early Christian sanctuary famous for its gold mosaic decorations. Once a Benedictine priory, a dependency of Moissac from the 11th Century onwards, it was taken over by the Maurist congregation in the 17th Century. When the Basilica was built, the previous organ was sold to Pamiers Cathedral in 1775. The Works Committee convened in 1860 to consider the acquisition of a new organ. Poirier and Lieberknecht, who had been craftsmen at the Maison Daublaine, were commissioned to rebuild the organ. The case was designed by M. Villeneuve. The woodwork was carved by the cabinetmaker Lacassin (who had produced the cases of Saint-Nicolas and Pibrac). The instrument was accepted on 28th of January 1864 by the Toulouse organists Leybach, Massis and Ponsan, among others. Lefébure-Wely inaugurated it on 18th of February 1864. The organ was presented at the Exhibition of 1865, winning a gold medal for Poirier & Lieberknecht. This was the builders' chef d'oeuvre, one of the most splendid examples of transitional construction, combining the great classical tradition (16-foot plenum, cornets, reed stops, with all pipes cut to pitch length) with elements of the romantic style (large récit expressif, gamba and harmonic flute stops, romantic reed stops and Barker levers). The organ was renovated by Théodore Puget in 1889 and inaugurated by Débat-Ponsan on 21st of March 1889. At Débat-Ponsan's suggestion, it was decided on 3rd of January 1897 to instruct Théodore Puget and Son to install pneumatic traction on the récit. The pedalboard was equipped in the same way. Maurice Puget then became responsible for the instrument, carrying out certain modifications. The instrument was restored in 1990 by the organ builders Boisseau-Cattiaux who corrected some of the alterations from the past. This restoration was completed in 1992 and the inauguration took place on the 3rd and 4th of October 1992 with the organists Michel Bouvard, Jan Willem Jansen, Jean Boyer and Philippe Lefebvre.
