As it approaches its bicentennial in 2024-2025, Warren County will celebrate a remarkable history as well as its reputation for the cleanest waterways and richest farmland in New Jersey. Stemming from wilderness times well before the county’s official formation through 1824 legislation, the area’s earliest settlements were in Greenwich, Oxford Furnace, and Pahaquarry. Situated at the confluence of the Delaware and Musconetcong Rivers, Greenwich was the gateway for the northward migration of Quaker, German, and Scots-Irish settlers landing at Philadelphia. Oxford Furnace’s first pioneers arrived in 1726, but real growth followed the building of the furnace in 1741, creating Warren County’s first hub of commercial activity and population growth. In 1732, Abraham Van Campen built a mill in what became the tiny village of Calno in Pahaquarry, the southernmost settlement in a chain of Dutch villages extending down the Minisink Valley from Esopus (now Kingston), New York. Warren County’s agricultural heritage, in combination with eighteenth and nineteenth century innovations in transportation and industry, are important chapters in the rural American tradition.
