The Sloss Company's city furnaces, built in what is now the center of Birmingham, Alabama, in 1881-1882, produced pig iron for the foundry market until their close in 1970. / The Sloss Furnaces, the nucleus of an integrated ironmaking system which includes extensive surviving remnants of coal and iron ore mines, quarries, and coke ovens, are the most visible symbol of the Birmingham District's role as the nation's leading foundry iron producer from the late-19th century until the 1960s..
Sloss now is used to hold metal arts classes, a barbecue cookoff, an annual Halloween haunted house, Muse of Fire shows (whatever they are) and is a concert venue.
