Aquia Creek sandstone

Type of sandstone used in Washington D.C. construction

Aquia Creek sandstone is a brown to light-gray freestone used extensively in building construction in Washington, D.C. in the late 18th and early 19th centuries. Quarried at Aquia Creek in Stafford County, Virginia, the stone was valuable for its ease of shaping and the quarry's proximity to the tidewater portion of the Potomac River, 45 miles (72 km) south of Washington.
