An inside glimpse of the Lukens National Historic District.

The story of American steel parallels the growth of the Lukens National Historic District — humble beginings, stories of struggle and courage, and leaps in technology that changed the course of American history. Meet Rebecca Lukens, the first female American industrialist, and tour her home. Visit the gracious mansions of Terracina and Graystone, homes to Rebecca's daughter Isabella and grandson A. F. Huston. See the 1902 Executive Offices and learn how Lukens steel appeared in icons like the Space Needle, World Trade Center, and the USS Nautilus.
