The Steuben house and the two other houses are open for weekend events. The Steuben house is also open once or twice a month for evening lectures or programs. Check the Bergen County Historical Society website for a calendar of events.
We are involved with the Steuben House and I'd suggest you call or visit the website. Unfortunately they do not have the regular hours as they used to. Fortunately they still have events, lectures, tours, events etc.!
