Ingalls Building, First reinforced concrete skyscraper in Cincinnati, United States.
The Ingalls Building rises 210 feet with 16 floors, featuring white marble on lower levels, gray brick walls, and white terra cotta decorations at the top.
Completed in 1903, this concrete structure required two years of negotiations with city officials who doubted the stability of buildings taller than six stories.
This building altered construction methods across the United States by proving that reinforced concrete could successfully replace traditional steel frame construction techniques.
The structure now operates as the Courtyard by Marriott Cincinnati Downtown hotel, maintaining its original architectural elements while serving modern hospitality needs.
Engineers used a system of twisted steel bars inside concrete slabs to create a rigid structure, producing 100 cubic yards of concrete during each work shift.
