Stony Brook Grist Mill

Built in 1699 and reconstructed in 1751 after the collapse of its dam, the Stony Brook Grist Mill has experienced multiple periods of disrepair and restoration, including significant efforts in the late 1940s and 1980s.

In the spring of 2024, the mill underwent another phase of restoration under the direction of millwright Amy Boyce. Working alongside her, we corrected earlier repairs, repaired and replaced components of the mill’s drive and gear systems, and returned the mill to a functional state using traditional methods and materials consistent with its historic construction.
