Rouen Cathedral contains a tomb of Richard the Lionheart which contains his heart. His bowels were buried within the church of the Chateau of Châlus-Chabrol in the L. It was from the walls of the Chateau of Châlus-Chabrol that the crossbow bolt was fired, which led to his death once the wound became septic. His corporal remains were buried next to his father at Fontevraud Abbey near Chinon and Saumur, France. Richard's effigy is on top of the tomb, and his name is inscribed in Latin on the side.
Rouen Cathedral was the tallest building in the world (151 m) from 1876 to 1880.
The cathedral was bombed in 1944, taking several direct hits that narrowly missed destroying key pillars.
