As the saying goes – they probably seemed like good ideas at the time. The world is peppered with examples of incredible engineering projects and buildings designed to make life easier for those that used them, amaze those that came to see them, and make money for those that ordered, designed and built them. They were the stuff of dreams. Often enormous engineering problems had to be resolved, obstacles overcome and new innovations employed just to get them built in the first place. Alas, a great number of these remarkable structures have now been abandoned, cast aside like enormous expensive out-of-date toys, never to be used in the ways for which they were intended. Each and every one of these extraordinary places is home to a wealth of powerful and compelling stories.
