The location of this building has been updated from TL 86768 82940 to TL 8677 8304. The co-ordinates included in the English Heritage description (S1) indicate a building on the school grounds south of the road, but it has been verified that this is actually one of the buildings north of the road, within the site of the Dominican church (NHER 5750).
