The Organ Chest: in 1982, the organ-builder Pascal Quoirin carried out the latest renovation. Considered one of the masterpieces of contemporary organ-making, this magnificent organ chest allows the Organa Festival to be held here, bringing together the best large organ players from around the world from July to September every year. This Festival, whose free concerts take place every Saturday at 5.30 p.m. in July, August and September, is exceptional due to the superb acoustic quality and the virtuosity of the performers.
