The Story

Established in 1804, the McClurg Iron Foundry was Pittsburgh's first air foundry, casting metal in a young industrial city perched at the gateway to the West. During the War of 1812 it forged cannons and ammunition, much of it destined for the American fleet that would contest control of Lake Erie. In 1835 the site achieved another milestone, producing the first locomotive steam engine built west of the Allegheny Mountains.

Why it matters

The foundry marks Pittsburgh's early rise as an iron-making powerhouse, arming the nation in wartime and helping launch the railroad age that would open the American interior.

Allegheny County

Pittsburgh, PA

When Allegheny County was carved out of Westmoreland and Washington counties in 1788, its seat at Pittsburgh was already a generation old β€” laid out in 1764 at the strategic forks where the Allegheny and Monongahela join to form the Ohio, a gateway that had drawn soldiers, traders, and settlers pushing west. Incorporated as a city in 1816, Pittsburgh grew into one of the great engines of American industry, its furnaces and mills pouring out the iron and steel that earned the region its "Workshop of the World" reputation. The county's story runs straight from a frontier river junction to the smoke-and-fire heart of the nation's industrial age.

Steamboat "New Orleans"

Pittsburgh, PA Β· est. 2011

On October 15, 1811, the side-wheeler New Orleans slid into the Monongahela near Suke's Run β€” the first steamboat ever built west of the Alleghenies. Its launch proved that steam power could conquer the powerful currents of the Ohio and Mississippi, and Pittsburgh, already rich in iron and timber, quickly became a bustling yard for building the boats that carried a nation west.

Pennsylvania Canal

Pittsburgh, PA Β· est. 1958

Here at Pittsburgh lay the western end of Pennsylvania's ambitious Main Line of Public Works, the state-built system of railroad, canal, and the remarkable Allegheny Portage Railroad that hauled canal boats over the mountains between 1826 and 1834. This loading basin was where eastern and western Pennsylvania met, and where goods transferred for the long journey across the state. By 1857 the great public work had been sold to the Pennsylvania Railroad, which soon rendered the canals obsolete.

John A. Roebling (1806-1869)

Pittsburgh, PA Β· est. 1996

John A. Roebling was a German-born engineer whose faith in twisted wire cable transformed how Americans crossed their rivers. Here in Pittsburgh in 1846 he built one of the first wire-rope suspension bridges to carry a road over the Monongahela, proving a design he would refine across the country. His genius culminated in the Brooklyn Bridge, whose plans he drew before his death in 1869 left its completion to his son Washington.
