We read about the Falkirk Wheel in the guidebook, and had to go. Near Stirling, it's a modern engineering marvel. Scotland has many canals (and rivers, lakes, etc.) which were the sole transportation for goods and people across the country, until the railroads and modern trucking. As part of a Millenium project, the Scotish Waterways has been restoring old abandoned canals. Originally, the lower canal joined the upper canal through eleven locks (!) which certainly took some time. Now, this recently installed (2002) "boat lift" brings vessels from the lower canal to the upper canal in less than 10 minutes. It's not only an amazing feat of technology, it's also really beautiful!
