Douai (Dutch: Dowaai) is a commune in the Nord département in northern France. It is a sub-prefecture of the department. Located on the river Scarpe some 40 km from Lille and 25 km from Arras, Douai is home to one of the region's most impressive belfries. The population of the metropolitan area, including Lens, was 552,682 in 1999.

A barge is a flat-bottomed boat, built mainly for river and canal transport of heavy goods. Some barges are not self-propelled and need to be towed by tugboats or pushed by towboats. Canal barges, towed by draft animals on an adjacent towpath, contended with the railway in the early industrial revolution, but were outcompeted in the carriage of high-value items due to the higher speed, falling costs, and route flexibility of rail.
