The Norman priory church, founded in 1119, by the wealthy Robert de Brus of Skelton, was, unfortunately, burnt down on May 16, 1289. Walter of Hemingburgh, a canon of Guisborough, has written a quaintly detailed account of the origin of the fire. Translated from the monkish Latin, he says 'On the first day of rogation-week, a devouring flame consumed our church of Gysburn, with many theological books and nine costly chalices, as well as vestments and sumptuous images; and because past events are serviceable as a guide to future inquiries, I have thought it desirable, in the present little treatise, to give an account of the catastrophe, that accidents of a similar nature may be avoided through this calamity allotted to us. On the day above mentioned, which was very destructive to us, a vile plumber, with his two workmen, burnt our church whilst soldering up two holes in the old lead with fresh pewter. For some days he had already, with a wicked disposition, commenced, and placed his iron crucibles, along with charcoal and fire, on rubbish, or steps of a great height, upon dry wood with some turf and other combustibles. About noon (in the cross, in the body of the church, where he remained at his work until after Mass) he descended before the procession of the convent, thinking that the fire had been put out by his workmen. They, however, came down quickly after him, without having completely extinguished the fire; and the fire among the charcoal revived, and partly from the heat of the iron, and partly from the sparks of the charcoal, the fire spread itself to the wood and other combustibles beneath. After the fire was thus commenced, the lead melted, and the joists upon the beams ignited; and then the fire increased prodigiously, and consumed everything.' Hemingburgh concludes by saying that all that they could get from the culprits was the exclamation, 'Quid potui ego?' Shortly after this disaster the Prior and convent wrote to Edward II., excusing themselves from granting a corrody owing to their great losses through the burning of the monastery, as well as the destruction of their property by the Scots. But Guisborough, next to Fountains, was almost the richest establishment in Yorkshire, and thus in a few years' time there arose from the Norman foundations a stately church and convent built in the Early Decorated style.
