Impressive elevator for boats on the Canal du Centre, Belgium.

Some more information from Wikipedia:

The Strépy-Thieu boat lift (French: L’ascenseur funiculaire de Strépy-Thieu) lies on a branch of the Canal du Centre in the municipality of Le Rœulx, Hainaut, Belgium. With a height difference of 73.15 metres (240.0 ft) between the upstream and downstream reaches, it is the tallest boat lift in the world, and will remain so until the Three Gorges dam boat lift in China is finished.
