This is a historical marker for an old grist mill in Windsor. Its located on the Northbound side of Route 75(Poquonock Ave.) just in front of Larsen’s Hardware. The marker was placed in 1933 and reads«The Warham Mill was established by Mr. John Warham, first minister to the Windsor Church, in 1640. The mill has been in continuous use as a grist mill to the present day. Tradition says it was the first grist mill in Connecticut.» Not really sure if the mill is still in operation today, as opposed to being in operation when the marker was placed 80 years ago. I kind of doubt that it is.
