Grand-Hornu, a remarkable 19th-century industrial site, is not only a testament to Belgium's coal mining history but also a UNESCO World Heritage site since 2012. Originally built by Henri De Gorge between 1810 and 1830, it represents a unique example of functional town-planning from the era. Today, Grand-Hornu is a cultural hub, housing contemporary art, architecture, and design exhibitions, reflecting a successful transformation from an industrial past to a vibrant present.
