The first mill at Greenbank was reportedly called the Swede's Mill dating from 1677. Not much is known of this mill except a vague description and undeciphered archaeological remains. In the 1760's, the present gristmill was built as a merchant mill to export flour. Every Friday and Saturday visitors are invited to join the millers, textile workers, wives and children who live and work at Greenbank Mill. Tours include the gristmill restoration, the Madison Factory textile mill, the Philips House, and the 19th century farm with heritage livestock.
