Industrial heritage refers to the physical remnants of industrial activities, including buildings, machinery, and infrastructure that reflect a society's industrial past. This heritage can include factories, mills, railroads, and other structures that played a significant role in economic development and technological advancement. Preserving industrial heritage is important for understanding history and culture, as it provides insight into the lives of workers and the evolution of industries. Sites like the Iron Market in Port-au-Prince or the Ruhr Valley in Germany serve as examples of how industrial heritage can be celebrated and maintained for future generations.
