where does the c and o canal start
Chesapeake and Ohio Canal The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch,"[1] operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
History of the British canal system The claim for the first pure canal in Great Britain is debated between "Sankey" and "Bridgewater" supporters.[15] The first true canal in the United Kingdom was the Newry Canal in Northern Ireland constructed by Thomas Steers in 1741.
