to Gudum Church ostensibly because a flood had destroyed the chapel and 'other buildings' which had fallen into the river. No evidence remains of the original priory site. The consecration of the new priory to St. Thomas Vigilie took place in 1492. The priory was built onto the north side of the church. While no trace of the priory remain, it may be supposed that it was built in Gothic style with pointed arches and constructed out of red bricks, the most common building material of the time. It was a small house, perhaps no more than 20 nuns, if that many, at any given time. Stubber Priory, a close neighbor, often had only ten or twelve, which may be more accurate for Gudum as well.
