This traditional cache is located at the historical marker for a grist mill in the late 1700's, and sawmill built in the mid 1800's and a blacksmith shop built in the early 1900's.
The buildings no longer exist, but this nice marker was placed by the Hopkinton Historical Commission to mark the location. Be sure to read about the site before you leave the location...and look see if you can spot the two swans that live on the pond across the street.
There is convenient parking closeby. Be sure to bring your own pen.
