Built in 1838, the mill capitalized on the discovery of high-quality limestone near Roundtop Hill. This discovery proved fortuitous, as the limestone was perfectly suited for producing hydraulic cement, a crucial building material of the time. Cement produced here found its way to iconic structures like the Washington Monument, the Cabin John Bridge, and even the U.S. Capitol dome, leaving a lasting mark on American history.

The ruins of this old cement factory are right along the side of the C&O Trail, and an informative signpost details the history. The Round Top Cement Mill was operative between 1838 and 1909, and was constructed opportunistically during the digging of the canal when workers encountered a pocket of argillomagenisian limestone.
