The Pennsylvania State Capitol - Commonwealth Treasure
Harrisburg, Dauphin County, Pennsylvania
Marker Inscription
The Pennsylvania Historical and Museum Commission declares the Pennsylvania State Capitol a Commonwealth Treasure For all to protect and preserve as a vital architectural and artistic monument to government by and for all Pennsylvanians
Erected by Pennsylvania Historical and Museum Commission
The Story
Dedicated in 1906, the Pennsylvania State Capitol was hailed by President Theodore Roosevelt as 'the handsomest building I ever saw.' Designed in an Italian Renaissance style and crowned by a dome inspired by St. Peter's in Rome, its interior is a showcase of murals, tile floors, and sculpture by leading American artists of the era. The Commonwealth Treasure designation honors it as both an artistic achievement and the working seat of Pennsylvania's government.
Why it matters
The Capitol embodies the Progressive Era's civic ambition—the belief that a democratic government deserved architecture and art worthy of the people it served.
The story behind this marker
AI contextThe era
By the opening years of the twentieth century, Pennsylvania stood at the industrial heart of the nation. Its steel, coal, and railroads helped power an American economy that was expanding at a dizzying pace, and Harrisburg, the capital on the banks of the Susquehanna River, was the seat from which a booming, ambitious Commonwealth governed itself.
This was the height of what historians call the Progressive Era, a time when reformers pushed governments to be cleaner, grander, and more accountable to ordinary people. It was also the age of the "City Beautiful" movement, when Americans believed that dignified public architecture could lift civic life and inspire good citizenship.
A capitol worthy of that vision did not come easily. An earlier statehouse had burned, and a partly finished replacement had stalled. The building dedicated in 1906 was Pennsylvania's answer to a hard question: what should the people's own house look like when a great state finally decides to build it right?
People & events
The Capitol you see today was the work of Pennsylvania architect Joseph Huston, who imagined the building as a "Palace of Art" where architecture, painting, and sculpture would speak together. He filled it with the labor of leading American artists and craftspeople of the era, so that murals, sculpture, tilework, and stained glass all carry a common theme: the story and promise of the Commonwealth.
The dome, rising over Harrisburg, took its inspiration from the great domed churches of Europe, and the interior was finished with a richness meant to rival any public building in the country. When the Capitol was dedicated in 1906, President Theodore Roosevelt attended and, by tradition, pronounced it the handsomest building he had ever seen.
Nearly a century later, in 2001, the Pennsylvania Historical and Museum Commission placed this marker to declare the Capitol a Commonwealth Treasure. The gesture was more than ceremony. It named the building an object of stewardship, something every generation of Pennsylvanians is asked to protect and pass on.
Its place in the American story
State capitols are among the most revealing buildings in America. They are where citizens go to petition, to protest, to celebrate, and to watch their laws being made, and their design broadcasts what a state believes about itself. Pennsylvania's Capitol is one of the boldest statements of that kind ever built.
It embodies a distinctly American idea born in the Progressive Era: that a government of and for the people deserves architecture and art as fine as anything a monarchy or a cathedral could command. The building insists that democracy is worth grandeur, and that public splendor belongs to everyone, not to a privileged few.
The Commonwealth Treasure designation carries that idea forward. It reminds visitors that a working seat of government can also be a shared work of art, and that preserving such a place is itself an act of civic faith.
If you visit
The Capitol sits at the center of Harrisburg, and it is very much a living building, so you may find lawmakers, staff, and school groups moving through the same halls you are exploring. That mix of everyday government and soaring art is part of the experience.
Let your eyes travel upward. Look for the great dome overhead, the sweep of the main staircase, the murals set into walls and ceilings, and the patterned tile beneath your feet. Take your time with the details, because this is a building that rewards slow looking rather than a quick pass-through.
Harrisburg makes an easy stop on a Pennsylvania road trip, close to the Susquehanna riverfront and within reach of the state's Civil War country and its river towns. Come to the Capitol to stand inside the Commonwealth's most ambitious statement about itself, and to see what a democracy built when it decided to build something beautiful.

Pennsylvania Fish and Boat Commission
Susquehanna Township, PA · est. 2016
Just after the Civil War, Pennsylvania's rivers were being fouled by industrial pollution and blocked by dams that cut off the migrating fish that once filled them. In 1866 Governor Andrew Curtin signed a law creating a state commission to restore those waters and fisheries, among the earliest such bodies in the nation. From hatcheries to habitat protection and law enforcement, the agency grew into a model that other states and federal programs would follow.
Daniel Drawbaugh
Lower Allen Township, PA · est. 1965
Daniel Drawbaugh, born in this village in 1827, was a self-taught mechanic who claimed to have devised a working telephone and sought a patent in 1880. Bell Telephone contested his claims, and in 1888 the courts decided in Bell's favor, leaving Drawbaugh a fascinating footnote in the contested history of the telephone. He worked on his inventions here until moving to nearby Camp Hill in 1904, where he died in 1911.
Henszey's Wrought Iron Arch Bridge
East Pennsboro Township, PA · est. 2004
Patented in 1869 by Joseph G. Henszey and built the same year by Philadelphia's Continental Bridge Co., this wrought iron bowstring arch truss is an early survivor of the bridge-building boom that followed the Civil War. It first carried traffic over Trout Creek in Slatington, was relocated in 1900 to span Ontelaunee Creek, and in 2002 moved again to Summerdale to carry pedestrians. Few of its kind remain.
Three Mile Island Historical Marker
Londonderry Township, PA
On March 28, 1979, a combination of equipment failures and human error at Three Mile Island's Unit 2 reactor triggered the worst commercial nuclear accident in U.S. history. Over several tense days radiation escaped, part of the reactor core melted down, and thousands of nearby residents fled their homes. The crisis gripped the nation and became a defining moment in the debate over atomic energy.
