Sloss Furnaces is a National Historic Landmark in Birmingham, Alabama in the United States. It operated as a pig iron-producing blast furnace from 1882 to 1971. After closing it became one of the first industrial sites (and the only blast furnace) in the U.S. to be preserved and restored for public use. In 1981 the furnaces were designated a National Historic Landmark by the United States Department of the Interior.
The site currently serves as an interpretive museum of industry and hosts a nationally recognized metal arts program. It also serves as a concert and festival venue. Construction is also underway on a new $10 million visitors center. The furnace site, along a wide strip of land reserved in Birmingham's original city plan for railroads and industry, is also part of a proposed linear park through downtown Birmingham. An annual Halloween haunted attraction called "Sloss Fright Furnace" is held at the site.(Wikipedia)
