Pennsylvania stretches from the shore of Lake Erie to the Delaware River, encompassing Appalachian ridges, plateaus and broad river valleys. Near the state’s geographic centre, the West Branch Susquehanna and its tributaries run through forested country, while the main Susquehanna continues south towards Chesapeake Bay. Philadelphia gives Pennsylvania an enduring place in the story of the United States: Independence Hall was the setting for the adoption of the Declaration of Independence and the signing of the Constitution. Former industrial cities, Amish and Mennonite communities, farms and state forests reveal markedly different sides of the Commonwealth.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
