The mission of the Sandwich Historical Society is to collect and preserve the material culture and historical record of the town of Sandwich, and to use these resources in service of the town through educational programs and exhibits.
Most of the furnishings are appropriate to the modest homes of the farmers, artisans, and shopkeepers of the 19th century who lived and worked in Sandwich. The work of early local painters, Albert Gallatin Hoit, Fred G. Quimby and summer resident E. Wood Perry, are well represented in the current collection.
Each winter a major exhibit utilizing the museum's collections is prepared and is open throughout the summer. Recent exhibits have featured the Quimby School of Sandwich, the development of spinning, basket makers of Sandwich, early maps and twentieth century Sandwich crafts.
