America turns 250 this year. Frederick's German roots go back even further.
Long before the United States existed, waves of German immigrants carved out a new life along the Monocacy River Valley in Maryland, planting the seeds of what would become Frederick County. And one of the most remarkable surviving pieces of that story is waiting for you to visit right now.
Schifferstadt Architectural Museum is Frederick County's oldest house open to the public — and it's a National Historic Landmark, the highest historic honor in the country.
Here's the story: In 1729, Joseph and Cathrina Brunner led three generations of their family from the war-ravaged Palatinate region of Germany to Philadelphia. By 1736, they had followed the Monocacy River south into Frederick County, settling a 303-acre tract they named Schifferstadt — after their hometown back in Germany.
In 1758, their son Elias and his wife Albertina built the stone house that still stands today.
What makes Schifferstadt so extraordinary is what's inside. Step through the cross-and-bible doors and you'll find:
▪️Two-foot-thick stone walls built to last centuries
▪️A radiant heating system that is the only one in America still in its original location
▪️A barrel-vaulted cellar that served as the colonial refrigerator
▪️Four bedrooms, a massive kitchen, and a tightly winding staircase to the second floor
The U.S. Department of the Interior designated Schifferstadt a National Historic Landmark in 2017, recognizing it as one of the finest examples in America of how German settlers wove their cultural heritage into frontier life — Georgian on the outside, distinctly Germanic on the inside.
And the connection to Germany is alive today: Schifferstadt is one of Frederick's sister cities,
As America celebrates 250 years, take a moment to go further back and discover the German pioneers who helped build this corner of the republic.
Tour the house, wander the award-winning Heritage Garden (a faithful recreation of a colonial four-square kitchen garden), and catch one of the special events, including the beloved Schifferstadt Oktoberfest this October.
Open weekends 2–5 p.m. | Appointments available through Frederick County Landmarks Foundation.
