During my recent sojourn in Edinburgh, I wen toi see the Falkirk Wheel. As an engineering project, I think it is at least as impressive as the London Eye, although far less known.
It is a 30 metre high rotary boat lift, that connects two canals in Scotland. The whole thing is plastered with boasts about Scottish engineering, although I notice that the firm that did the engineering had an address in Derbyshire.
This is a view from the top.
