Choir organ of Notre-Dame de Paris Cathedral

The choir organ of Notre-Dame Cathedral is a pipe organ located inside the Paris cathedral with two keyboards of 56 keys each and 28 sound stops. The instrument received its current mechanical components in 1969 while housed in an original case from 1863.

The organ case dates from 1863 and was designed by architect Eugène Viollet-le-Duc. The pipe mechanism was rebuilt in 1969 by Robert Boisseau, following several earlier instruments created by different builders over time.

The organ accompanies daily services in the cathedral and shapes the sound experience during religious ceremonies. It plays an essential role in the worship and musical life that visitors witness inside.

The instrument sustained water damage during the 2019 cathedral fire and is currently undergoing reconstruction as part of the cathedral's broader restoration. Visitors can observe the progress on future visits as work continues toward completion in 2026.

The Gothic case from the 1800s remains the only original component that will be preserved during the upcoming restoration. This makes the outer design a living link to the past while the inner workings receive modern improvements.
