Gettysburg Beyond the Battle Museum

Located in historic Gettysburg, Pennsylvania, the Adams County Historical Society preserves over three centuries of remarkable history. and has over one million historic items in its care. Over the years, it has been housed in several temporary locations that were too small to provide public access to the breadth of its collections. Historical documents and artifacts have been stored in a variety of off-site locations in less than optimal conditions.

In 2020, the Historical Society initiated a capital campaign to build a new Museum, Archives, and Education Center to preserve treasured historic artifacts and share the remarkable story of one of America’s most famous communities. Isett provided MEP design engineering for the new two-story 29,000-square-foot museum and a one-story 4,000-square-foot Archives Barn.

Isett provided the HVAC, plumbing, electrical, fire protection and security systems for the complex, working with the Museum Exhibit Designer, Phoenixx Design Associates, LLC, to provide the required environmental controls in the main Museum Building as well as the Archive Barn. These systems include temperature and humidity control, and LED exhibit lighting.
