Marblehead Museum is a 501 (c) (3) nonprofit organization that independently owns and operates three properties The 1768 Jeremiah Lee Mansion, the J.O.J. Frost Gallery, and The Civil War and Grand Army of the Republic Museum. Our mission is to preserve, protect, and promote Marblehead’s past as a means of enriching the present. 2018 marks the 250th anniversary of the Lee Mansion and we invite you join us for a year of celebration!
