Scottish boat elevator - The Falkirk Wheel

The world’s first and only rotating boat elevator, the Falkirk Wheel.

The Falkirk Wheel, named after the nearby town of Falkirk in central Scotland, is a rotating boat lift connecting the Forth and Clyde Canal with the Union Canal. The difference in the levels of the two canals at the wheel is 24 metres, roughly equivalent to the height of an eight story building.

On 24 May 2002, Queen Elizabeth II opened the Falkirk Wheel as part of her Golden Jubilee celebrations. The opening had been delayed by a month due to flooding caused by vandals who forced open the Wheel's gates.
