On the eastern bank of the Lamprey River in Durham, New Hampshire, this three-acre site preserves the remains of a nineteenth-century mill complex that became one of the town’s main industrial centers. Industrial activity began in 1835 with Moses Wiggin’s timber dam and sawmill, and expanded in 1854 when Thomas Wiswall added a power canal and paper mill. After the paper mill burned in 1883 and flooding damaged the dam in the 1890s, the sawmill was abandoned. Visible remains include mill foundations, waterworks, the partly filled canal, the 1912 concrete dam, and submerged traces of the earlier timber dam. Later adapted for hydroelectric power, the property was acquired by Durham in 1967 and listed on the National Register in 1988.
