Forest Hills, Allegheny County, Pennsylvania
Marker Inscription
Gateway to the West and steel center of the world. Named for William Pitt by Gen. Forbes after the fall of French Fort Duquesne in 1758. Laid out as a town by John Campbell in 1764. Incorporated as a city, 1816.
Erected by Pennsylvania Historical and Museum Commission
The Story
The forks of the Ohio, where the Allegheny and Monongahela join, were among the most fought-over ground in colonial America. After General John Forbes forced the French to abandon Fort Duquesne in 1758, the point was renamed for William Pitt, laid out as a town in 1764, and chartered as a city in 1816. From that frontier outpost grew the steelmaking colossus that supplied the nation's rails, bridges, and armaments.
Why it matters
As the gateway to the West and later the heart of American steel, Pittsburgh links the colonial contest for the continent to the rise of the nation's industrial power.
The story behind this marker
AI contextThe era
The forks of the Ohio — where the Allegheny and the Monongahela come together — were among the most fiercely contested places in colonial America. Control of that river junction meant control of the route into the vast trans-Appalachian interior, and in the mid-1700s two empires were willing to fight for it.
France held the point with Fort Duquesne; Britain was determined to take it. The struggle here was one theater of a much larger war between the two powers for dominance in North America, waged through hard marches across mountains and forests far from any city.
Out of that violent contest grew a settlement that would become one of the most important places in the country. But its origins lie in this earlier world of frontier forts and imperial ambition, when the future of the continent was still genuinely undecided.
People & events
In 1758, the campaign led by General John Forbes brought the contest to a head. As his expedition closed in, the French abandoned and destroyed Fort Duquesne rather than hold it, and the British occupied the strategic point at the forks.
Forbes gave the place a new name in honor of William Pitt, the British statesman then directing the war — a nod to the leadership in London credited with the empire's changing fortunes. The site's future was now tied to Britain and, soon, to the settlers pressing westward behind the army.
In 1764, John Campbell laid out the settlement as a town, and in 1816 it was chartered as a city. From a burned frontier fort to an incorporated municipality in under sixty years — the transformation traces the arc of the early American frontier itself.
Its place in the American story
This ground links two of the biggest themes in American history: the colonial struggle for the continent and the industrial rise of the nation. The fall of the French fort here was a key moment in deciding who would command the western interior, and the town that followed became a gateway for the settlement of the West.
Generations of westward-bound Americans passed through this junction, where the settled East gave way to the water routes leading into the frontier. The site's location made it a natural threshold, and it wore that role for a long time.
Later, the same place became a colossus of steelmaking, supplying the rails, bridges, and armaments of a growing nation. The story that begins with an imperial war for a river junction ends with the forging of the country's industrial backbone — one continuous thread running through a single point on the map.
If you visit
You are in the greater Pittsburgh area, a short distance from the famous meeting of the three rivers that gave this place its importance. Even from the surrounding communities, it is worth orienting yourself toward those forks and imagining the armies that once maneuvered for them.
Markers like this one, set a little away from the point itself, are a reminder that the history radiated outward — the contest and the growth touched the whole region, not just the riverbank. Take a moment to picture the wilderness that once stretched west from here.
This makes a fine companion stop on a drive through the area's past. Trace the story from the colonial forts to the industrial mills, and let the landscape connect the frontier outpost to the steel city it became.

Pittsburgh
Pittsburgh, PA · est. 1946
When British General John Forbes captured the smoldering ruins of French Fort Duquesne in 1758, he renamed the strategic point where three rivers meet in honor of British statesman William Pitt. The little town laid out in 1764 sat at the literal doorway to the trans-Appalachian frontier, and by the time it became a city in 1816 it was already funneling settlers and goods westward. In the century that followed, its furnaces and mills earned it a global reputation as the steel capital of the world.
Steamboat "New Orleans"
Pittsburgh, PA · est. 2011
On October 15, 1811, the side-wheeler New Orleans slid into the Monongahela near Suke's Run — 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.
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 — 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.
John Scull (1765-1828)
Pittsburgh, PA · est. 1958
In 1786, when Pittsburgh was still a raw frontier town at the forks of the Ohio, the Berks County native John Scull printed the first edition of the Pittsburgh Gazette—the first newspaper published west of the Allegheny Mountains. From his home and print shop here, Scull carried the printed word into the trans-Appalachian West and took an active hand in the region's civic affairs. His paper endured, becoming the Post-Gazette in 1927.
