For some industrial history, take some time to see Sloss Furnaces. A National Historic Landmark, these blast furnaces have been turned into a museum devoted to the forging of iron in the early 20th century. The great smokestacks and stoves make an impressive and eerie sight. (Rock concerts are frequently held there.) 20 32nd St. N., Birmingham. Phone 205-324-1911. http://www.slossfurnaces.com.
