A monastery is founded on the current Cathedral site, at that time called Medeswell, later Medehamstede (“the home/farmstead in the water meadows”), located on the north bank of the River Nene. The monastery was founded by Peada, son of King Penda of Mercia, and completed by Peada’s brother Wulfhere. At that time Mercia was a pagan Saxon kingdom, but as part of a marriage contract with neighbouring Christian Northumbria, Christian missionaries were allowed to found a religious house here. The original monastery may have been built of timber, but seems to have been later replaced in stone. These original monks were Celtic Christians.
