The Eighth Maine Regiment Memorial was built in 1891 in Peaks Island, in Casco Bay, which is part of the city of Portland, Maine. It initially served as a summer vacation lodge for the Civil War veterans of the Eighth Maine Regiment with the capacity to accommodate annual reunion events. Today, it is managed by descendants of the veterans of the Eighth Maine Regiment and still serves as a lodge as well as a memorial structure, containing a museum and library that honours the Civil War.
