Before the Norman conquest a small Saxon chapel dedicated to St Peter stood outside the east gate of Shrewsbury; it had been built by Siward, son of Ethelgar and a close relative of Edward the Confessor. There was still a landowner, known as Siward the Fat, in Shropshire at Domesday, although he had owned many more estates in 1066. He must have been the donor of the two estates the church is known from Domesday to have held in 1066: at Boreton near Condover and Lowe near Farley. However, the Abbey had lost Lowe by 1087.
