At the confluence of the Monongahela and Allegheny rivers, where they merge to form the Ohio, the British built a fort and named it after the prime minister of the time, William Pitt.

Things have changed a bit since then, and the City of Pittsburg stands high and proud over he point where the three rivers meet, and the location George Washington picked to defend the British Empire.

One room of the fort still stands, opposite he heights of Mount Washington, where you can clime for a fantastic vista of the whole city.
