With the support of several patriotic women, many who were Daughters of the American Revolution, the Old Barracks Association brought the south section of the barracks in 1902, and opened it as a museum in 1903. The state of New Jersey bought the north section in 1914 for the museum. Throughout the year, the museum offers special events, including celebrations of the Battles of Trenton, George Washington's birthday, African-American history, and women's history. Historical interpreters, wearing period dress, explain colonial and Revolutionary New Jersey. The museum's 1998 restoration re-created the barracks and hospital rooms, which are used for special school programs.
Documentation includes photographs and brochures.
