Phoenixville is a borough in Chester County, Pennsylvania, United States, 28miles (45km) northwest of Philadelphia, at the junction of French Creek with the Schuylkill River. The population is 16,440 as of the 2010 Census. Originally called Manavon, Phoenixville was settled in 1732 and incorporated as a borough in 1849. In its industrial heyday early in the twentieth century, it was an important manufacturing center and it was the site of great iron and steel mills such as the Phoenix Iron Works, boiler works, silk mill, underwear and hosiery factories, a match factory, and the famous (and now highly collectible) Etruscan majolica pottery. Like so many American towns and cities, Phoenixville owes its growth to its waterways. It is not only situated on the broad Schuylkill River, a historic thoroughfare to Native Americans and early settlers alike, but it is bisected by the fast-flowing French Creek, which was quickly harnessed for water power.
