Warren Heritage Museum at Bread Lock Park (Lock 7 West) is a premiere site along the historic Morris Canal Greenway. Lock 7 West became known as "Bread Lock" because the store at the end of the lock sold goods to boatmen passing through in the mid-19th c., including homemade bread and pies. The museum features models and displays of Warren County history with emphasis on the Morris Canal, Lenape habitation, and more, primarily in the Warren Heritage Scenic Byway area of the county. The park, which is open dawn to dusk, includes a full-size replica of a Morris Canal boat, a storybook trail along the Morris Canal, and walking/exercise trails.
