The tympanum inside the pediment above the Saint Stephen Portal on Notre-Dame’s southern facade is decorated by bas-reliefs which recount the life of the first Christian martyr, Saint-Étienne, according to the Acts of the Apostles. On the right is the base of the cathedral’s famous spire, designed by Eugène Viollet-le-Duc in 1859 as part of his exhaustive renovations of the church; the spire was destroyed in the fire of April 15th 2019.
