A National Historic Landmark, the Ledyard Water-Powered Up-Down Sawmill is an 11-acre park with an operating up-and-down saw that is powered by water as it passes from a two-acre mill pond through a horizontal turbine. The mill features a working blacksmith shop and 19th century Lane shingle mill, grist mill and mill artifacts of the Industrial Revolution. Picnic tables adorn the tree-trimmed grounds that surround the pond, making it an ideal venue for warm-weather outings. Admission is free.
