Pennsylvania is where America declared itself a nation and where, four score and seven years later, it nearly came apart. The Declaration of Independence and the Constitution were both signed in Philadelphia. Washington’s army survived the brutal winter at Valley Forge. The Civil War turned on the fields of Gettysburg. And on a September morning in 2001, the passengers of Flight 93 fought back over a field in Somerset County. Few states carry more of the American story.
I taught American history for decades, and Pennsylvania’s sites anchor so much of what I tried to teach. Here are 15 historic sites in Pennsylvania I think are worth visiting, counting down to my favorite. A mix of National Park Service units, state sites, and privately run landmarks. At More Than Just Parks, we cover all of it.
Let’s get started.

15. Duquesne Incline
We begin in Pittsburgh with a charming relic of the industrial age that still runs every day. The Duquesne Incline, opened in 1877, is a steep cable railway that hauls passengers up Mount Washington in beautifully preserved wooden cars, delivering one of the finest city views in America.
117 public lands destinations are under threat. Get the free briefing that 27,000+ people use to stay informed and take action.
Built to carry workers up the hillside in the era of the steel mills, the incline is owned by Pittsburgh Regional Transit and operated by a nonprofit preservation society. A small museum at the top explains the city’s many inclines, most of which are long gone. Ride it at dusk for the best view of the three rivers.
14. Fort Ligonier
In the Laurel Highlands town of Ligonier, a fully reconstructed fort brings the French and Indian War to life. Fort Ligonier was a British stronghold during the 1758 campaign to take Fort Duquesne, and it withstood a French and Native attack that October.
A young George Washington served in this campaign, and the site’s museum holds an excellent collection of 18th-century artifacts, including a pair of pistols once owned by Washington. Run by a private nonprofit, it is one of the best-presented colonial military sites in the state.
13. Erie Maritime Museum
On the Lake Erie waterfront, the Erie Maritime Museum tells the story of the Battle of Lake Erie, the 1813 naval victory in which Oliver Hazard Perry famously reported, “We have met the enemy and they are ours.” The museum is the home port of the Brig Niagara, a sailing reconstruction of Perry’s relief flagship.
A timing note for 2026: the Niagara has been out of the water for a major refit. It is expected to return to Erie around early July 2026, with sailing resuming later in the summer. If seeing the ship under sail is your goal, check the schedule before you plan your trip.
12. Washington Crossing Historic Park
On Christmas night 1776, George Washington led his ragged army across the ice-choked Delaware River for a surprise attack on the Hessians at Trenton, a desperate gamble that revived the dying Revolution. Washington Crossing Historic Park preserves the embarkation point on the Pennsylvania side.
One correction worth noting: this is a Pennsylvania state park, managed by the Department of Conservation and Natural Resources, not a federal site. December 2026 marks the 250th anniversary of the crossing, and the park’s annual reenactment is a stirring tradition. It is a fine place to stand where the tide of the Revolution turned.
11. Johnstown Flood Museum
On May 31, 1889, the South Fork Dam failed and sent a wall of water into Johnstown, killing more than 2,200 people in one of the deadliest disasters in American history. The Johnstown Flood Museum, in a historic library building downtown, tells the human story of that catastrophe.
Now operated under the Heritage Johnstown banner, this private nonprofit museum features an Academy Award-winning documentary and moving exhibits on the flood and its aftermath. Do not confuse it with the national memorial at the dam site, which is our next entry. They are two distinct places, about ten miles apart, and both are worth your time.
10. Johnstown Flood National Memorial
About ten miles from downtown, the Johnstown Flood National Memorial sits at the remains of the South Fork Dam itself, the structure whose failure unleashed the disaster. This is the National Park Service site, and standing at the breach where the dam gave way gives you a chilling sense of the scale of what happened.
The dam had been poorly maintained by an exclusive sportsmen’s club whose members included some of the wealthiest men in America. The memorial’s visitor center lays out the chain of negligence that led to so many deaths, a sobering early lesson in corporate accountability.
9. Allegheny Portage Railroad National Historic Site
Here is an ingenious solution to a problem most people never think about. In the 1830s, Pennsylvania’s canal system hit a wall at the Allegheny Mountains. The answer was the Allegheny Portage Railroad, a series of inclined planes that hauled entire canal boats up and over the ridge on rails powered by stationary steam engines.
It was an engineering marvel of its day, the first railroad tunnel in the country among its features. The national historic site preserves the inclines and a reconstructed engine house, telling the story of how a young nation moved goods across a mountain barrier before the age of through railroads.
8. Hopewell Furnace National Historic Site
In the countryside near Elverson, Hopewell Furnace preserves one of the best-surviving examples of an early American iron plantation. From 1771 to 1883, this self-contained village smelted iron ore into everything from stoves to cannons for the Continental Army.
The national historic site recreates the world of the ironmaster, the molders, the colliers, and the farmers who made the operation run. Costumed interpreters demonstrate the crafts of the era, and the surrounding fields and forests show how completely the furnace depended on the land. It is a vivid look at early American industry.
7. Thaddeus Kosciuszko National Memorial
In Philadelphia stands the smallest unit in the entire National Park System, at just 0.02 acres. The Thaddeus Kosciuszko National Memorial honors the Polish military engineer who came to America and became a hero of the Revolution, designing the fortifications at West Point and fighting for the Patriot cause.
The memorial occupies the boarding house room where Kosciuszko lodged in 1797 and 1798. It is open on a limited schedule, generally weekends from noon to 4, so plan accordingly. For its tiny size, it tells an outsized story about the international idealists who helped win American independence.
6. Fort Necessity National Battlefield
In the Laurel Highlands, a small circular stockade marks the spot where a 22-year-old George Washington fought, and lost, his first battle. In July 1754, French and Native forces surrounded Washington’s hastily built Fort Necessity and forced his surrender, an opening shot of the French and Indian War.
The conflict that began here would become a world war and reshape the map of North America. The national battlefield preserves the reconstructed fort and an excellent interpretive center. It is humbling to see where the future commander in chief took his first, faltering steps as a soldier.
5. Flight 93 National Memorial
On September 11, 2001, the 40 passengers and crew of United Flight 93 learned of the attacks on New York and Washington and chose to fight back, storming the cockpit and forcing the hijacked plane down in a field in Somerset County rather than letting it reach its target in the capital.
The Flight 93 National Memorial honors their sacrifice with quiet dignity. The Wall of Names, the boulder marking the impact site, and the soaring Tower of Voices all invite reflection. It is among the most moving places in the country, a monument to ordinary people who acted with extraordinary courage in their final minutes.
4. Eisenhower National Historic Site
Adjacent to the Gettysburg battlefield sits the only home Dwight and Mamie Eisenhower ever owned. After commanding the Allied forces in Europe and serving two terms as president, Ike retired to this working farm, where he hosted world leaders and tried, finally, to relax.
The Eisenhower National Historic Site preserves the house and farm much as the Eisenhowers left them. Access is by shuttle from the Gettysburg visitor center. Touring the home, you meet the private man behind the general and the president, and you understand why he chose to spend his final years on this quiet Pennsylvania farm.
3. Valley Forge National Historical Park
The winter of 1777 to 1778 nearly broke the Continental Army. Encamped at Valley Forge, Washington’s men endured cold, hunger, and disease that killed some 2,000 soldiers. Yet they emerged in the spring a disciplined fighting force, drilled into shape by the Prussian officer Baron von Steuben.
Valley Forge National Historical Park preserves the encampment grounds, with reconstructed log huts, Washington’s headquarters, and miles of trails across the rolling fields. The story here is not of a battle but of endurance, the moment the army survived its darkest hour and the Revolution lived to fight on.
2. Gettysburg National Military Park
Over three days in July 1863, the largest battle ever fought in North America raged across the fields and ridges around Gettysburg. When it ended, more than 50,000 men were dead, wounded, or missing, and Lee’s invasion of the North had been turned back. It is widely regarded as the turning point of the Civil War.
Four months later, Abraham Lincoln came here to dedicate the soldiers’ cemetery and delivered the Gettysburg Address, redefining the meaning of the war in just 272 words. Gettysburg National Military Park preserves the battlefield with hundreds of monuments and an outstanding museum. No place better conveys the scale of the war’s sacrifice.
1. Independence National Historical Park
At the top of my list is the birthplace of the nation. Independence National Historical Park in Philadelphia takes in the ground where the United States was created. In Independence Hall, the Declaration of Independence was adopted in 1776 and the Constitution was drafted in 1787. The building is a UNESCO World Heritage Site.
Across the street, the Liberty Bell draws visitors from around the world, and it is free to see. The park also includes Congress Hall, the site of Benjamin Franklin’s home, and much more within a few walkable blocks. No single place holds more of the founding story. Stand in the room where the founders argued, signed, and gambled everything, and you understand why this earns the top spot.
