In the early hours of 18 July 2020, a fire broke out in three parts of the cathedral, one concentrated on the main organ ("grand orgue") at the west end, originally built by Jacques Girardet in 1621, which was destroyed, a second near a smaller organ to the left of the altar and the third to the right of the altar. Around 100 firefighters tackled the blaze. Police investigated the incident as a possible act of arson. Fire Chief Laurent Ferlay reported that the cathedral sustained less damage than Notre-Dame de Paris did in its 2019 fire.
