The Flat River Historical Museum stands on the most historic site in Greenville. It was here in Greenville, Michigan that John Green, of Fulton County, New York, chose to build his cabin in 1844; and with the help of his brother-in-law, Samuel Demorest, and Demorests' sons, Clark and Samuel, constructed a dam across the Flat River and built a sawmill. With a vast forest of white pine on the North bank of the river the history of Danes in Michigan began.
After the Christmas Parade on December 3, 2010, Santa will be at the Museum to meet with children. Stop in to see the beautiful Nutcracker Display.
