Historic Gristmills of America

Discover 166 of America's historic gristmills and watermills — water-powered grain mills, some turning since the 1600s, scattered along creeks and back roads from New England to the Pacific. Tap any mill on the map to hear its story read aloud: who built it, how its great wheel and millstones worked, and the town it fed. Everything works fully offline, so the stories play even where there's no signal — on a country drive, a covered-bridge detour, standing beside the mill race. Browse all 166 across dozens of states, see what to look for when you visit, and let each mill's story begin as you arrive. Free to explore three featured mills; one simple unlock opens the full catalogue — no subscription, ever.
