As the official repository for the municipalities of Alnwick/Haldimand, Brighton, Cobourg, and Cramahe, we hold government records from the past 200 years, including:
• Council and committee minutes
• Assessment rolls
• Collectors rolls
• Birth, marriage, and death registrations
• Land abstracts and deeds
• Architectural plans
Over 300 individuals and organizations have donated items dating from the early 19th century to the present day. Each record enriches the story of the social, political, economic and built evolution of our County. We have collections from the private sector ranging in type:
• Letters, diaries, journals
• Business and organizational records and correspondence
• Military maps, notebooks, publications, medals
We are working towards having as many of our items digitized as possible. This is a large task so please be patient with us as we move our images and information into our new collection management program.
We want to develop an inclusive and diverse collection that tells the history of communities from all across Northumberland County. We prioritize the collection of materials from currently under-represented municipalities, groups and subjects including:
• Trent Hills
• ethnic cultures, families, and individuals
The Northumberland County Archives is open to the public for research, tours, and educational programming. We collect, care for and provide access to archival materials that represent the stories of the people, places and development of Northumberland County.

We are in the C. Gordon King Centre in Cobourg, a short walk from downtown and the waterfront, sharing a building space with the Cobourg Public Library.
We are constructing a new Northumberland County Archives facility in Cobourg, scheduled to open in 2022. Our Archives will share an innovative new building space with the County’s long-term care facility. We will have an expanded reading room, program space, storage rooms, and conservation lab. We are excited to collaborate with our community partners to ensure a future for our past.
