Colonial Williamsburg is a living-history museum and private foundation presenting a part of the historic district in the city of Williamsburg, Virginia. Its 301-acre (122 ha) historic area includes several hundred restored or recreated buildings from the 18th century, when the city was the capital of the Colony of Virginia; 17th-century, 19th-century, and Colonial Revival structures; and more recent reconstructions. The historic area includes three main thoroughfares and their connecting side streets that attempt to suggest the atmosphere and the circumstances of 18th-century Americans. Costumed employees work and dress as people did in the era, sometimes using colonial grammar and diction.

An open-air museum is a museum that exhibits collections of buildings and artifacts outdoors. It is also frequently known as a museum of buildings or a folk museum.
