A chapel dedicated to St Catherine of Alexandria is known to have existed on the site since 1157, when the Prior of Durham agreed to allow Romanus de Hilton to appoint his own chaplain for the chapel, subject to the prior's approval. In return, de Hilton was to provide an annual contribution of 24 sheaves of oats for every draught ox he owned, to the nearby monastery at Monkwearmouth, and was required to attend the mother church of St Peters for the feasts of the Nativity, Easter, Whitsuntide and Saints Peter and Paul. In 1322, there was a chantry dedicated to the Virgin Mary and there were three chantry priests in 1370.
