Billings Estate Museum

The Billings Estate National Historic Site is a heritage museum in Ottawa, Ontario, Canada. It is located at 2100 Cabot St. in the former home of one of the region's earliest settlers. The oldest wood-framed house in Ottawa was built in 1827-9 by Massachusetts-born Braddish Billings. It became the home for the following four generations of the Billings family. It is Ottawa's oldest surviving house, though the Bytown Museum building is older. Billings had moved to the area in 1812, and was the first settler in Gloucester Township.

Billings became prosperous in the timber trade and built the large home that was named Park Hill. Billings later moved into agriculture, and the house became the centre of a large and prosperous farm providing produce for Bytown, with the farm linked to the town by the Bytown and Prescott Railway.
