In 2010, the Carnegie Library building became the Cumberland County Military Museum. The Cumberland County Historical & Genealogical Society had purchased and refurbished the building with the help of grants, donations and volunteer labor.
The Cumberland County Military Museum was established to honor veterans from Cumberland County who sacrificed their jobs, families, and lives in the defense of a way of life, in battles from the Mexican War through the present conflicts in the Middle East.
The museum recording studio and viewing room were designed to record oral history about the lives and military service of local veterans and the stories of individuals, events, and places in the County. Moreover, the Cumberland County Military Museum displays military photos, clothing, documents, posters and other artifacts to give new appreciation and a gesture of gratitude to those who served, fought, and died for freedom and justice.
