Pottstown is a borough in Montgomery County, Pennsylvania, United States about 40 miles (55 km) northwest of Philadelphia and 20 miles (32 km) southeast of Reading, on the Schuylkill River.
Modern-day Pottstown is established on land originally deeded to William Penn. Germans, Swedes and English were among the first European settlers in the area. After establishment of the first iron forge in 1714, Pottstown's fortunes became tied to the iron industry.Eventually, blast furnaces for production of iron and later steel opened in the area. Iron and steel production brought the Potts family, iron masters by trade, to the area. They established a forge in the area and built a large home just west of the Manatawny Creek. John Potts founded a town in 1761 on part of the 995 acres (4.03 km2) that he owned. It is the home of the nations oldest mills, Pottstown Roller Mill.Over time, Pottsgrove grew and in 1815, was incorporated under the name Pottstown becoming the second borough in Pennsylvania after Norristown.
