Whispers of history echo around the Clopper Mill Ruins. These weathered remnants hold stories of industry, intrigue, and even a brush with presidential history. The Clopper Mill Ruins, as they stand today, are a shell of their former self. Yet, they offer a glimpse into a bygone era.
The Clopper Mill Ruins began as a simple grist mill in the 1770s, harnessing the power of Seneca Creek. In 1812, Francis Cassatt Clopper bought the property. He added to the existing mill, using bricks from his own Woodlands estate. The mill thrived under his ownership, becoming a vital part of the local economy. The mill expanded to include a sawmill and initially used an overshot wheel, which was later converted to an undershot wheel. The ruins you see today reveal layers of this history. Notice the mix of stone and brick. The original mill used stone. The top layer of brick marks Clopper’s additions.
The Clopper Mill Ruins weren’t just a place of business. They played a small but fascinating role in national history. In April 1865, George Atzerodt, a co-conspirator in the Lincoln assassination plot, sought refuge here. He was supposed to assassinate Vice President Andrew Johnson. However, Atzerodt lost his nerve and fled Washington. He found temporary shelter at Clopper Mill, unknowingly weaving the mill into the narrative of a pivotal moment in American history. He spent a night hiding at the mill before his capture and subsequent execution.
Tragically, a fire in 1947, set by an arsonist, destroyed the mill. Now only the ruins remain, a poignant reminder of its industrious past. Today, the Clopper Mill Ruins are part of Seneca Creek State Park, though they remain undeveloped. Their location in the flood plain means nature continues to reclaim them. Standing here, you can almost hear the whir of the mill wheel and imagine the lives touched by this once bustling center of commerce. The echoes of its past linger, offering a captivating story for those who listen closely.
