The name of Gorgopotamos became famous during World War II, when 150 Greek partisans, following plans drawn by E. C. W. "Eddie" Myers and assisted by a group of British SOE officers, which included C.M. Woodhouse, blew up the railroad bridge on November 25, 1942 as part of "Operation Harling" and cut off the enemy-controlled route between Thessaloniki and Athens. The blast ruined two of the six poles of the bridge. In an act of reprisals, the German occupation forces executed 16 Greek locals. The area around the bridge has been designated a national monument.
