Earl Tostig made Tynemouth his fortress during the reign of Edward the Confessor. By that time, the priory had been abandoned and the burial place of St Oswin had been forgotten. According to legend, St Oswin appeared in a vision to Edmund, a novice, who was living there as a hermit. The saint showed Edmund where his body lay and so the tomb was re-discovered in 1065. Tostig was killed at the Battle of Stamford Bridge in 1066 and so was not able to re-found the monastery as he had intended.
