 The two towers survived the devastating fire of 1194, which destroyed most of the cathedral except the west facade and crypt.As the cathedral was rebuilt, the famous west rose window was installed between the two towers (13th century), and in 1507, the architect Jean Texier (also sometimes known as Jehan de Beauce) designed a spire for the north tower, to give it a height and appearance closer to that of the south tower.This work was completed in 1513.
