During the middle of the 20th century, Plymouth underwent a number of urban re-development projects in the area, culminating in the re-constructed Jenney Grist Mill upon the same location as the original in 1969, with some parts, including the millstones, having been salvaged from a 19th century mill in Pennsylvania.
