The Larsson-Noak Historic District encompasses a collection of buildings constructed by Swedish immigrants to northern Maine between about 1888 and 1830. The district is focused on a cluster of four buildings on Station Road, northeast of the center of New Sweden, Maine. Notable among these is the c. 1888 Larsson-Ostlund House, which is the only known two-story log house built using Swedish construction techniques in the state. Across the street is the c. 1900 Noak Blacksmith Shop, a virtually unaltered building housing original equipment. The district was listed on the National Register of Historic Places in 1989.
