The village is also home to a historic mill. Officially known as the Saddle Rock Grist Mill, it was built circa 1700 and is located inside a small cove that opens onto Little Neck Bay off Long Island Sound. The mill is listed in the National Register of Historic Places and is the oldest continually operating tidal grist mill in the United States. The mill is now owned and operated by Nassau County as a working museum open to the public. The mill has been restored to its mid-19th-century appearance and is located on Grist Mill Lane in Saddle Rock.
