A large portion of the Billings Estate National Historic Site artefact collection received Canadian Cultural Property designation in 1996 because of its significance as material evidence of the historic development of the nation's capital. The eclectic collection contains more than 27,000 artefacts - many of which are on exhibition at the museum - that belonged to the family and their neighbours, including furniture, household goods, personal possessions, an extensive library, tools, entomological specimens, agricultural equipment, and a 1959 Cadillac.
The Billings Estate National Historic Site is located in the centre of Ottawa in the Alta Vista neighbourhood near the intersection of Bank Street and Riverside Drive.
