In these unprecedented times, we need your help, now more than ever ! As a non-profit organization, we rely on museum admissions, Museum Shop purchases and donations to support all our efforts.
Hammond Castle Museum has stood on the Gloucester shore for nearly 100 years and been open to the public for much of the last century. Recently, it has undergone an incredible transformation from a quiet museum and wedding venue to a rejuvenated and vibrant member of the Cape Ann community with freshly created exhibits, popular children’s programs and events to engage the greater community. We are steadfast in our mission to educate as set forth by our founder, John Hays Hammond Jr. and are poised to become one of the leading STEM museums in Essex County. Hammond Castle Museum is a 501(c)(3) non-profit organization and is listed on the National Register of Historic Places.
