Naper Settlement, established in 1969, is a 12-acre (49,000 m²) outdoor history museum accredited by the American Alliance of Museums that consists of a collection of thirty historical buildings and structures from the Naperville, Illinois area. Many buildings were moved here from their original locations and refurbished in a style fitting of their time periods that range from 1831 when Naperville was founded through the early 20th century. Visitors can come for hands-on activities and tours led by museum educators in period costume.
