The Story
In 1774, on the eve of the Revolution, Thomas Johns—soon to serve as a colonel in the Continental cause—joined Georgetown merchant Thomas Richardson to raise flour mills along the reliable current of Rock Creek. Grinding grain into flour for the growing capital region, mills operated on this site for roughly a century, outlasting the men who built them and falling silent only in the 1870s. In an age before steam, a dependable creek was industrial infrastructure, and Rock Creek's waters turned the stones that fed Georgetown's wharves and tables.
Why it matters
Water-powered grist mills like these were the quiet engines of early America, converting a young nation's farmland into marketable flour and knitting rural fields to port-city commerce long before the factory age.
The story behind this marker
AI contextThe era
In 1774, the land along Rock Creek was part of a young and restless Chesapeake countryside. Tobacco had long ruled the region's fields, but wheat was rising fast, and with it came a hunger for mills to grind grain into flour that could be barreled, shipped, and sold. Just downstream, Georgetown was growing into a busy little port, its wharves crowded with hogsheads bound for distant markets.
This was the eve of revolution. Within two years the colonies would declare independence, and Montgomery County itself would be carved out of Frederick County in 1776, named for a general who fell at Quebec. The people building mills here were putting down stakes in a world about to be remade.
Rock Creek was the reason any of it was possible. In an age before steam, moving water was power — the only power strong enough to turn heavy millstones day after day. A dependable creek with a good fall of water was a kind of infrastructure, as valuable in its way as a road or a wharf.
People & events
Two men set this place in motion. Thomas Johns, who would serve as a colonel during the American Revolution, joined with Thomas Richardson, a prominent Georgetown merchant, to raise flour mills on the banks of Rock Creek. It was a natural partnership for the moment: a man of the countryside and a man of the port, betting together that the region's wheat would keep coming and that someone had to turn it into flour.
Their timing was bold. To build in 1774 was to invest in the future of a place whose political fate was still unsettled. While Johns would take up the soldier's part in the war, the mills themselves carried on the quieter, essential work of feeding people — grinding grain that fed households, armies, and the trade that ran through Georgetown's wharves.
What is most striking is how long the enterprise outlasted its founders. Flour mills stood and worked on this site for roughly a century, falling silent only in the 1870s. The men who built them were long gone, but the water kept turning the stones.
Its place in the American story
Water-powered grist mills like these were among the quiet engines of early America. They did unglamorous but foundational work: converting a young nation's farmland into a marketable commodity. Flour could be stored, shipped, and sold far from where the wheat was grown, and mills were the hinge that connected inland fields to port-city commerce.
The long life of the Newport mills — from 1774 into the 1870s — traces almost the entire arc of America's water-power age. For a hundred years, before steam and rail reshaped everything, the surest way to build industry was to find a reliable stream and harness its fall. Countless communities grew up around exactly this logic, clustering near the mill that turned their harvest into cash.
That the mills here went quiet in the 1870s is its own small chapter of the national story. By then, steam power and railroads were pulling milling toward large mechanized operations in growing cities, and the creekside mill that had served generations gradually gave way to a new industrial era.
If you visit
Come to Rock Creek and let the water do the explaining. The creek that once powered these mills still runs south through its wooded valley toward Georgetown and the Potomac, and standing beside it you can hear the same steady current that turned the stones for a hundred years.
Let yourself imagine the scene: the low rumble of the millworks, wagons arriving heavy with grain and leaving with barreled flour, the smell of ground wheat in the air. What is peaceful parkland today was once a working place, humming with the practical business of feeding a region.
This is a fine stop to fold into a day exploring Rock Creek's long green corridor. Slow down, follow the water, and think about how much of early American life depended on a good creek and a set of turning stones — infrastructure so ordinary in its time that it is easy, now, to walk right past where it stood.

Chain Bridge
Arlington, VA
In 1797, the merchants of Georgetown spanned the Potomac at the Little Falls, raising the first bridge across the river in a bid to capture trade that might otherwise flow downstream to the rival Virginia port of Alexandria. The original Falls Bridge let wagons hauling goods from Virginia's "upper country" roll directly into Georgetown, knitting the young capital region's commerce together. Repeatedly destroyed by floods and rebuilt over the decades, the crossing eventually took the name "Chain Bridge" from a chain-suspension version that once stood here.
The Mouth of Pimmit Run
Arlington, VA
Where Pimmit Run empties into the Potomac at the river's head of navigation, colonial Virginia planter Thomas Lee patented land in 1719 and, in 1742, established an official tobacco inspection warehouse. In the tobacco economy of the Tidewater, such government-licensed warehouses were vital chokepoints where the colony's signature crop was graded, certified, and prepared for shipment to Britain. This riverside spot grew into what's remembered as Arlington's first industrial complex, later associated with figures like Philip Richard Fendall in the years after 1794.
Ellicott's Mills
Baltimore County, MD
In 1772 three Quaker brothers from Bucks County, Pennsylvania — the Ellicotts — settled this steep granite valley on the Patapsco River and built flour mills that helped transform the surrounding farmland from tobacco to wheat. To move their flour to market they cut a road down to Baltimore, knitting the young port to its hinterland. Nearly six decades later, on May 20, 1830, the pioneering Baltimore & Ohio Railroad reached this very spot, making the milling town one of the first railroad destinations in the nation.
Great Railroad Strike of 1877
Baltimore, MD
In the depths of the long depression that followed the Panic of 1873, railroad companies slashed already-thin wages one time too many, and in July 1877 the anger boiled over. What began among Baltimore and Ohio Railroad workers in Martinsburg, West Virginia, and here in Baltimore quickly leapt from city to city along the rail lines, becoming the first genuinely nationwide strike in American history. For roughly six weeks, freight sat idle, factories fell silent, and clashes between strikers, militia, and federal troops left dozens dead before the movement was suppressed.
