The Billings Estate National Historic Site is an Ottawa museum 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. The estate also includes a historic cemetery that contains graves dating back to 1820.
