Falkirk - Falkirk Wheel (stopped)
Here's the static version so people can see what the wheel normally looks like. From Wikipedia:
The wheel raises boats by 24 metres (79 ft), but the Union Canal is still 11 metres (36 ft) higher than the aqueduct which meets the wheel. Boats must also pass through a pair of locks between the top of the wheel and the Union Canal. The Falkirk Wheel is the only rotating boat lift of its kind in the world.
