The Rittenhousetown Historic District was an early industrial community where the first paper mill in British North America was built by William Rittenhouse and his son Nicholas on the north bank of Monoshone Creek near Philadelphia, Pennsylvania. Flax was woven into linen in nearby Germantown. When the linen fabrics wore out, the rags were brought to Rittenhousetown to be made into paper. Paper produced at the Rittenhouse mill was sold to printers in Germantown, Philadelphia, and New York City. In 1890, Rittenhousetown became part of the Germantown section of Philadelphia.
