The fabric of the cathedral suffered from vandalism and plunder, and by 1574 it was in sufficiently bad condition to attract the attention of the Glasgow town council: "the greit dekaye and ruyne that the hie kirk of Glasgow is cum to, throuch taking awaye of the leid, sciait and wther grayth thairof in this trublus tyme bygane sua that sick arte greit monument will alluterlie fall doun and dekey without it be remidit".[13] The condition was serious enough to encourage the town council to raise a tax of £200 for repairs to the cathedral in that same year, but the process of repairing the cathedral and modifying it for presbyterian worship dragged on for years.[14] Many of the windows were bricked up, in 1578 the lead of the cathedral roof was repaired, and in 1579 the members of the Glasgow Trades House defended the cathedral from further depredation, enabling it to survive the Reformation relatively unscathed.
