This monument of industrial archaeology is a memorial to an idealistic -- or paternalistic -- employer. Mine-owner Henri de Gorge (1774-1832) constructed the complex between 1810 and 1830 in neoclassical style, and attached to it some 450 well-designed and well-equipped houses for his workers. Fallen into disuse and dereliction, Grand-Hornu was bought in the 1970s by a local architect and restored. It's a fascinating, unlikely mixture of antiquarian sensibility and gritty industrial reality that showcases the Victorian entrepreneurial tradition at its best. A part of the site has been given over to exhibits of contemporary art.
