About Greenwich Township
Greenwich is one of the oldest township communities in what is now Warren County. The area was settled in the late 17th century, appears in official records by 1738 and was formally incorporated as a New Jersey township on February 21, 1798. Over time, portions of the once-vast township became several other Warren County municipalities.
Stewartsville is the best-known community within Greenwich Township and developed as an important crossroads of road, canal and rail transportation. Upper Stewartsville and newer residential areas extend the community beyond the historic village core.
History & Historic Places
The Kennedy House and Mill is listed on the National Register of Historic Places and reflects Greenwich Township's early milling, agricultural and political history.
The organization works to preserve and interpret the township's social, cultural, architectural and natural history.
The historic church and cemetery area is deeply connected to the township's colonial and Revolutionary-era story.
Morris Canal & Transportation Heritage
County parkland along the Morris Canal Greenway with trails, interpretation and access to the Inclined Plane 9 West historic site.
Warren County's current historic-site planning describes Plane 9 West as one of the canal's most exceptional inclined planes, with a rise of about 100 feet and an overall length approaching 1,600 feet.
Greenway segments preserve portions of the canal corridor and connect Greenwich with neighboring Lopatcong and Franklin Township canal sites.
The museum at Plane 9 West is currently listed by Warren County as temporarily closed, while the surrounding historic site and park remain important canal destinations.
Greenwich shares in the Route 57 transportation story associated with Thomas Edison's Portland cement and one of New Jersey's earliest concrete highway sections.
The road through Greenwich is part of a much older regional transportation route that linked early Warren County settlements.
