Buttonball Farm - 25 Middle Valley Road

Once part of a larger tract owned by William Trimmer whose brother Lawrence owned a local rock quarry and peach basket factory, this vernacular Italianate house features a five over four façade with center door and rectangular windows with a pediment. The center hall construction with front and back door is a simple, symmetrical floor plan allowing for light and cross ventilation.

Museum Closed Until Further Notice

The Historical Society Museum will be closed until further notice. The long awaited restoration work on the Union Schoolhouse (Historical Society & Washington Township Museum) has begun. Last year the Morris County Freeholder's awarded funds from the Morris County Preservation Trust Fund to be used towards exterior restoration at the circa 1830 schoolhouse, the oldest school in the township extant. The Historical Society is providing the matching funds. We apologize for the inconvenience.

The Washington Township Historical Society aims to bring together people interested in the history of Washington Township, Morris County, the state of New Jersey, and promote a better appreciation of our American heritage.


We support historical programs, archives, publications, preservation, markers, and historical collections in our museum. We are a nonprofit organization that is federally recognized as tax-exempt under section 501(c)(3) of the Internal Revenue Code.
