Sally Ann Furnace Complex
Why it's listed
Sally Ann Furnace is an iron plantation in Topton, Berks County, built around a furnace established by Valentine Eckert in 1791 beside Sacony Creek. At its height in the 1820s the estate covered 450 acres and included about 20 buildings, employing 150 men in furnace and farm work. Under the Hunter family, the furnace produced about 30 tons of pig iron weekly in the late 1820s, and it manufactured cannonballs for the Union Army during the Civil War. The furnace closed in 1869 and reopened for only two years about a decade later. Most industrial structures survive only as ruins. The mansion house, begun in 1814 by Jacob Hunter for his bride, is a 2½ story stuccoed stone building with five bays, six-over-six sash windows, a sunburst transom, and circular attic windows. Its interior retains heart hemlock woodwork and English hardware, and it is regarded as one of the most architecturally significant houses in the county. The c. 1820 stone store and the granary also remain.
Significance in brief: The nomination argues the complex was a major link in eastern Pennsylvania's iron industry in the first half of the nineteenth century, and that its mansion house is one of the most imposing and architecturally significant houses in Berks County. It cites the Hunter family's ironmaking enterprise and the furnace's wartime production of cannonballs for the Union Army.
