The lifts on the old Canal du Centre are a series of four hydraulic boat lifts near the town of La Louvière, classified both as Wallonia"s Major Heritage and as a World Heritage Site. Along a particular 7km 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. 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 rise, opened in 1917. These lifts were designed by Edwin Clark of the British company Clark, Stansfield & Clark.
The lifts were part of the inspiration behind the Peterborough and Kirkfield Lift Locks in Canada. In the late 19th century Richard Birdsall Rogers visited the locks as to understand and study possible ideas for a lift lock system.
These industrial monuments were designated by UNESCO as a World Heritage Site in 1998. Of the eight hydraulic lift locks built in the late 19th and early 20th century, the four of the Canal du Centre are the only ones still functioning in their original form.
Since 2002, operation of the lifts has been limited to recreational use. Commercial traffic now bypasses the old lifts and is handled by the enormous Strépy-Thieu boat lift, whose rise of 73m was the highest in the world upon completion.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
