Long Significance Description:
The C&O Canal is a flat water canal, chartered in 1825. Construction began in 1828 and by 1850 the canal was opened to its terminus at Cumberland, Maryland. The canal ceased operations in 1924 due to flood damage and the buying out of the company by the Baltimore & Ohio Railroad. In 1938, the B&O Railroad sold the canal property to the US government for $2 million dollars. The entire 184.5 miles of the canal was recognized as a National Historic Monument in 1961, and then in 1971 became known as the Chesapeake & Ohio Canal National Historical Park. Under the 1966 National Historic Preservation Act, the Canal was added to the National Register of Historic Places, having historical significance merits under architecture, engineering, commerce, transportation, military history and conservation. A confirmation National Register was approved by the Keeper for the CHOH on August 9, 1979.

The purpose of the C&O Canal was to bring freight and produce from Cumberland, Maryland, to Georgetown. The canal is an excellent example of 19th c. canal building technology. The magnitude of the engineering achievement is exemplified by the 184.5 mile length of the canal, which includes 74 lift locks rising 605 feet. 11 stone aqueducts were constructed to carry the canal prism over large Potomac River tributaries and 241 historic culverts were built to carry smaller streams and roads under the canal. 7 supporting dams were also constructed. Among the noteworthy engineered works on the canal is the Paw Paw Tunnel, which was drilled through 3, 117 feet of bedrock.

The ruins, although they can not be identified, are representative of the development that occured along the canal. Many businesses or canal workers built structures along the canal.

Short Physical Description:
Located on the riverside of the towpath at Ernstville, these ruins consist of a rectangular foundation, cistern and square foundation. While the ruins' form, use and precise date are unknown, they may be related to the farmhouse located just across the canal here.
Long Physical Description:
There is also a farmed field just east of these foundations. There are concrete fence posts along the towpath, near the path to this field. The area of the ruins has daffodils, forsythia and periwinkle growing in profusion. The east side of this area is bordered by a creek and the square ruins sit atop the creek’s ravine.
