Tate House was opened as an historic house museum in 1935 by The National Society of the Colonial Dames of America in the State of Maine (NSCDA-ME). The NSCDA-ME is the Maine chapter of The National Society of The Colonial Dames of America (NSCDA), a lineage organization founded in 1891 by women dedicated to furthering an appreciation of our national heritage through historic preservation, patriotic service, and educational projects. The NSCDA-ME, a 501 (c)(3) non-profit corporation, owns Tate House and its collections; the museum has been managed and operated independently by Tate House Museum, Inc., in close cooperation with the NSCDA-ME since 2005. Tate House Museum is a separate 501 (c)(3) non-profit member-corporation that is governed (according to the Code of Ethics of the American Association of Museums) by a community Board of Directors.
Over the past several decades, the museum’s primary goals of preservation and education have developed and expanded. The raised bed herb garden, unique architecture, special tours and events have attracted a broad range of visitors. Tate House welcomes guests from across the country and around the globe. Students throughout the state benefit from Tate House’s resources and educational programs as they learn about the mast trade and life in the eighteenth century.
