Preserving Our Past to Protect Our Future
Working to protect our environment with the rural and historic
characteristics of our neighborhood.
About Us
In 1960, several area residents decided to form a historical society for Washington Township. Washington Township Historical Society (WTHS) was registered in New Jersey the following year. Christian Lanner, former mayor of the township, was elected the first president. In 1981, we opened our museum in the old stone schoolhouse that dates back to 1830.
