The New Castle Historical Society operates three historic buildings for guided tours for individuals and groups. The Society is also involved in educating the public about the history of New Castle through exhibits, programs, lectures, publications, and resource materials. The Society works to promote historical awareness and encourage the preservation of historical architecture and material culture of New Castle.

The New Castle Historical Society is an incorporated, non-profit membership organization, with 501 (C) 3 IRS status. Donations to the Society are therefore deductible. There is an 18-member Board of Directors, who oversee its management. Staff consists of an executive director, office manager, events marketing manager and staff and 16 guides. Nearly 50 volunteers work on various Society functions.

The Society was established in 1934 to save the Amstel House from an uncertain future. In 1946, the Delaware Society for the Preservation of Antiquities turned over the Dutch House to the Society for its second acquisition. Then in 1980, the Society reached an agreement with the Trustees of New Castle Common, to provide exhibits on town history at the Old Library Museum. Exhibits over the years have included such New Castle topics as education, a history of Italian-Americans, the wharf, shops and merchants in the town, African-American life, the Trustees of New Castle Common, and the architecture of the town.

The New Castle Historical Society celebrated 80 years of historic preservation in 2014!
