question: The organ at Notre Dame de Paris has how many pipes?
article: Notre Dame de Paris
candidates: Though several organs were installed in the cathedral over time, the earliest ones were inadequate for the building. The first noteworthy organ was finished in the 18th century by the noted builder François-Henri Clicquot. Some of Clicquot's original pipework in the pedal division continues to sound from the organ today. The organ was almost completely rebuilt and expanded in the 19th century by Aristide Cavaillé-Coll. The position of titular organist ("head" or "chief" organist) at Notre-Dame is considered one of the most prestigious organist posts in France, along with the post of titular organist of Saint Sulpice in Paris, Cavaillé-Coll's largest instrument. The organ has 7,374 pipes, with ca 900 classified as historical. It has 110 real stops, five 56-key manuals and a 32-key pedalboard. In December 1992, a two-year restoration of the organ was completed that fully computerized the organ under three LANs (Local Area Networks). The restoration also included a number of additions, notably two further horizontal reed stops "en chamade" in the Cavaille-Coll style. The Notre-Dame organ is therefore unique in France in having five fully independent reed stops "en chamade".
