Souther Tide Mill Dam, 610 Southern Artery, Quincy, Norfolk County, MA
Significance: It is significant as a relatively well-preserved example of a once common and now rare type of mill dam. Built ca. 1806 for Ebenezer Thayer, it is associated with the Souther Tide Mill which is one of two tide mills in Massachusetts and one of the less than ten tide mills that remain on the Atlantic seaboard. It is also a significant structure in the industrial history of Quincy both as a part of the oldest standing mill complex in the city and as the best-preserved element of the Quincy Canal (1826-1870)...
