Where Tradition Meets the 21st Century


The Mahoning Valley region was once the third largest steel producer in the world. Within the CASTLO communities the earliest settlers in Ohio established Town 1, Range 1 of the historic Connecticut Western Reserve. This is the home of the Hopewell furnace, the nation’s first blast furnace. This is the heartland of America’s industrial legacy.

The CASTLO Industrial Park revitalized 120 acres of the former Youngstown Sheet & Tube mill to create a premier, industrial park. Moreover, to build a new generation of talent, CASTLO established its Community Fund to build new programs and initiatives.

Twenty-First Century

Several of the Park’s 9 buildings have been renovated to accommodate virtually any enterprise, and an additional 70 acres is shovel-ready for new construction. The heritage buildings on CASTLO’s grounds could not be duplicated in a new industrial park today.

Handsome brick facades have been restored to their original beauty and stature and retrofitted with the best modern materials and design. They provide flexible working space from 4,500 to 62,000 square feet. These buildings are attractive, functional and easily adaptable.

The CASTLO Community Improvement Corporation is a non-profit organization founded in 1978 for the purpose of creating economic opportunity for Campbell, Struthers and Lowellville, Ohio. Over $5 million was invested to clean, level and landscape the 120 acre campus to attract new industry and prospective  employers to the region. The Board of directors consists of community leaders and elected officials from Campbell, Struthers, Lowellville, Coitsville and Poland.
