In 2001 the Historic Association opened the Millyard Museum in one of the renovated mill buildings of the Amoskeag Manufacturing Company. It is home to the permanent exhibit, Woven in Time, 11,000 Years at Amoskeag Falls, that tells the story of Manchester from the time of the earliest settlement to the present time. This, and the museum’s changing exhibits, include selections from the organization’s vast collections.

The Research Center, renovated in 2006, houses the Association’s library and archives where the records of the Amoskeag Manufacturing Company can be found along with archival collections of Manchester families, businesses and organizations. The Research Center maintains a large photograph collection, and has a collection of books, oral histories, ephemera, artwork ,manuscripts and other materials. Researchers may also access the Association’s collections of Native American artifacts, and other types of historical objects through the auspices of the Research Center.

The Association also provides educational programs for children and adults and organizes historic preservation initiatives.
