The Jefferson Township Historical Society is located in the historic Amos Chamberlain building, which was constructed in the early 1870s. The house is listed on the National Register of Historic Places as well as the New Jersey register. The society, which formed in 1971, acquired the building in the early 1980s and made badly needed renovations by 1984. Previously, it had been a library since 1960. Amos' son, George, and his wife lived in the house until the 1890s. The family rented the house until 1960.
