The College Archives contain records of the activities, administration, benefactions, finances and property of the College since its foundation in 1284. Estate deeds are concerned mainly with East Anglia and particularly Cambridgeshire and some date from the twelfth century.

The Archives are private, but may be consulted by advance appointment with the College Archivist. Applicants wishing to consult the Archives should write to the Archivist, Dr Roger Lovatt, at Peterhouse, Cambridge, CB2 1RD; a letter of reference may be required.
