Over one hundred years later the cathedral suffered much damage at the hands of the English during the destructive War of the Breton Succession and then by a fire at the end of 1353. After the fire, Bishop Guy de Montfort made the reconstruction a priority and started work on the choir which was completed between 1354 and 1357. Under de Montfort's successor, Hugues de Montrelais, whose bishopric ran from 1357 to 1375, the new cathedral was finished, but in 1394 the town was under siege again, this time by Olivier de Clisson and again was badly damaged. Now Bishop Guillaume Angier took charge of the reconstruction necessary and apart from the reconstruction of the choir, he finalised the long-awaited construction of the Tour Marie. Then Bishop Jean de Malestroit reconstructed the gable of the north wing of the transept and had a magnificent window installed there, sadly destroyed by the storm of 1735. By the beginning of the 15th century, the cathedral was finished and between 1460 and 1472, Bishop John Prigent began the construction of the chapel of the Annunciation. Finally, the nineteenth and twentieth centuries saw much restoration and important works including the repair of the vaulting and work on the window framing. As we have seen in this brief summary, the cathedral had to be rebuilt on many occasions this as a consequence of military attacks or natural disasters.
