 In June 1390 , Alexander Stewart , Robert III 's brother , burned the cathedral , manses and burgh of Elgin . This fire was very destructive , requiring the central tower to be completely rebuilt along with the principal arcades of the nave . The entire western gable between the towers was reconstructed and the main west doorway and chapterhouse were refashioned . The internal stonework of the entrance is late 14th or early 15th century and is intricately carved with branches , vines , acorns and oak leaves . A large pointed arch opening in the gable immediately above the main door contained a series of windows , the uppermost of which was a circular or rose window dating from between 1422 and 1435 . Just above it can be seen three coats of arms : on the right is that of the bishopric of Moray , in the middle are the Royal Arms of Scotland , and on the left is the armorial shield of Bishop Columba Dunbar ( Fig . 11 ) . The walls of the nave are now very low or even at foundation level , except one section in the south wall which is near its original height . This section has windows that appear to have been built in the 15th century to replace the 13th century openings : they may have been constructed following the 1390 attack ( Fig . 12 ) . Nothing of the elevated structure of the nave remains , but its appearance can be deduced from the scarring seen where it attached to the eastern walls of the towers . Nothing of the crossing now remains following the collapse of the central tower in 1711 . Elgin Cathedral is unique in Scotland in having an English style octagonal chapterhouse and French influenced double aisles along each side of the nave ; in England , only Chichester Cathedral has similar aisles . The chapterhouse , which had been attached to the choir through a short vaulted vestry , required substantial modifications and was now provided with a vaulted roof supported by a single pillar ( Figs . 13 & 14 ) . The chapterhouse measures 10 @.@ 3 metres ( 34 ft ) high at its apex and 11 @.@ 3 metres ( 37 ft ) from wall to opposite wall ; it was substantially rebuilt by Bishop Andrew Stewart ( 1482 – 1501 ) , whose coat of arms is placed on the central pillar . Bishop Andrew was the half @-@ brother of King James II . The delay to the completion of these repairs until this bishop 's episcopacy demonstrates the extent of the damage from the 1390 attack .
