From an abandoned New York rail line repurposed into a jaw dropping public park- to a former Danish Shipyard turned sunken museum -this global engineering series explores extraordinary structures, buildings, machines and gadgets which have been transformed from their original function into something entirely different. 

We discover the history of how and why they were originally built, but above all – the engineering prowess required for such mammoth repurposing projects-uncovering every step of how they metamorphosed from their original purpose into something completely new that preserves the past while providing function for the future.
