Pennsylvania Farm Show
Harrisburg, Dauphin County, Pennsylvania
Marker Inscription
First held in January 1917, the Farm Show took place each year at various Harrisburg locations until 1931, when it moved to the new Main Exhibition Building here. The Large Arena first opened for the 1939 show. From modest beginnings, the Farm Show ultimately grew into one of the world's largest indoor gatherings devoted to the celebration and promotion of agriculture.

The Story
First held in January 1917, the Pennsylvania Farm Show began as a modest winter gathering that rotated among Harrisburg venues before settling into a purpose-built Main Exhibition Building in 1931. The addition of the Large Arena for the 1939 show cemented its permanent home in the state capital. Over the decades it swelled into one of the largest indoor agricultural expositions on earth, a January fixture where farmers, breeders, and butter-sculptors converge.
Why it matters
The Farm Show reflects how deeply agriculture shaped Pennsylvania's identity and economy, turning a working industry into an annual public celebration that still draws hundreds of thousands.
The story behind this marker
AI contextThe era
In January of 1917, when the first Pennsylvania Farm Show opened in Harrisburg, agriculture was not a nostalgic backdrop to American life—it was the main event. Most Pennsylvanians still lived close to the land, and the state's farms fed its booming mill towns and cities. Winter was the natural season for such a gathering: crops were in, animals were housed, and farm families finally had time to travel, compare, and learn.
The early twentieth century was also an age of improvement and organization. Agricultural colleges, county fairs, and state commissions were all pushing to spread better methods—stronger seed, healthier livestock, smarter machinery. A statewide winter show fit that spirit exactly: bring the best of everything under one roof, in the capital, where the whole commonwealth could see it.
Harrisburg made sense as the host. As the seat of state government, it sat at the crossroads of Pennsylvania's rail and road networks, reachable from the dairy counties, the grain country, and the orchards alike.
People & events
The story this marker tells is one of steady, almost architectural growth. The Farm Show began without a permanent home, moving among various Harrisburg locations year after year through the 1910s and 1920s—a traveling celebration still looking for a place to settle.
That place arrived in 1931, when the show moved into a new Main Exhibition Building on this site. A wandering event finally had a roof of its own. Then, for the 1939 show, the Large Arena opened, giving the exhibition the grand indoor space that a first-rate livestock and equipment show demands.
Those two dates—1931 and 1939—are the hinges of the whole story. They mark the moment an idea became an institution: from a modest gathering that had to borrow space into a fixed, purpose-built complex that could keep expanding to match the state's ambitions for it.
Its place in the American story
What began as a regional winter meeting grew, by the marker's own account, into one of the world's largest indoor gatherings devoted to agriculture. That is a genuinely national kind of story: the transformation of a working industry into a public celebration of itself.
Across America, the county and state fair became one of the great civic rituals—a place where rural and urban citizens met, where prize animals and new machines shared the spotlight, and where a state took the measure of its own economy. Pennsylvania built one of the biggest and most enduring versions of that tradition, and did it indoors, in the dead of winter, when few others would try.
The Farm Show endures because it answers a permanent need: reminding a modern, city-dwelling public where its food actually comes from, and honoring the people who produce it. In that sense this Harrisburg complex speaks for farm country everywhere.
If you visit
If you come to the Farm Show complex, notice how the buildings themselves tell the tale on the marker: a Main Exhibition Building rooted here since the 1930s, and the great Large Arena that opened at the end of that decade. You are walking through the physical record of a small event that kept outgrowing its own walls.
The best time to feel it is in January, when the show is running and the halls fill with the sounds and smells of a working farm scaled up to enormous size—livestock, machinery, and food from every corner of the commonwealth. It is loud, crowded, and unmistakably alive.
For a road trip, this pairs perfectly with the nearby state capitol and Harrisburg's riverfront. See the seat of government, then come here to see the industry that fed the state that built it. Bring an appetite; celebrating Pennsylvania agriculture has always included tasting it.

Across Front Street stands the official home of Pennsylvania's governor, a Georgian Revival house completed in 1968.

The marker captures a quiet moment of civic continuity — the passing of one seat of state hospitality to another.
J. Horace McFarland
Harrisburg, PA · est. 1995
J. Horace McFarland was a Harrisburg printer whose passion for beauty made him a national force in the early conservation and civic-improvement movements. As longtime president of the American Civic Association, he championed the "City Beautiful" ideal—that clean, green, well-designed cities uplift their citizens. He fought successfully to protect Niagara Falls from industrial exploitation and campaigned for the creation of the National Park Service in 1916. A devoted rose grower, he edited the "American Rose Annual" for decades from his Breeze Hill home and gardens in Harrisburg.
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.
