The lifts on the old Canal du Centre are a series of four hydraulic boat lifts near the town of La Louvière in the Sillon industriel of Wallonia, classified both as Wallonia's Major Heritage and as a World Heritage Site (province of Hainaut). Along a particular 7 km (4.3 mi) stretch of the Canal du Centre, which connects the river basins of the Meuse and the Scheldt, the water level rises by 66.2 metres (217 ft). To overcome this difference, the 15.4-metre lift at Houdeng-Goegnies was opened in 1888, and the other three lifts, each with a 16.93 metres (55.5 ft) rise, opened in 1917.
