Cumberland Mills Historic District
- Also Known As: S D Warren Paper Mill
- Vicinity: Both sides of Presumpscot River between railroad tracks and Warren Ave
The S D Warren Historic District is the finest example in Maine of good urban planning in the area of its industrial plant. The architecture, layout, and construction of the company housing give the present visitor the sense of time and place which arises from being placed within an unusual example of planned company housing from the last quarter of the 19th century. - NRHP, 2 May 1974
