In French architecture, a flèche (French: "arrow") is a lead-covered timber spire, or spirelet. These are placed on the ridges of church or cathedral roofs and are usually relatively small. However, larger versions can be found on cathedrals such as Amiens Cathedral, Coventry Cathedral, and previously Notre-Dame de Paris, before its collapse in a 2019 fire that also destroyed the roof. The highest flèche in the world was built at the end of the 19th century for Rouen Cathedral. Its height is 157 metres (515 ft).
