The Historic Worthen House is Lowell’s oldest tavern and restaurant. Visitors step into the past, dining under a pressed tin ceiling, in a space once occupied by the likes of Edgar Allen Poe, Jack Kerouac, Jimmy Breslin and Ed McMahon. A beautifully restored, pulley-driven fan system - one of only four in the United States and the only existing set in its original location in the country - can be turned on at a patron’s request. In its early days, the fan was propelled by steam and served to keep flies off the dry goods. The intricate series of belts and pulleys each help operate the next decorative paddle fan. In its early days, the fan was propelled by steam; today it is powered by electricity.
