Las cuatro minas que integran este sitio cultural se extienden desde el este hasta el oeste de Bélgica, a lo largo de una franja de terreno de 170 kilómetros de largo y de 3 a 15 kilómetros de ancho. El sitio lo forman las zonas de minería del carbón mejor conservadas de todo el país, que se explotaron principalmente desde principios del siglo XIX hasta la segunda mitad del siglo XX. En este sitio se hallan muestras tempranas de la arquitectura utópica de los inicios de la primera Revolución Industrial europea, que forman conjuntos urbano-industriales sumamente integrados. El ejemplo más notable lo proporcionan la mina y la ciudad obrera del Grand-Hornu, planeadas en la primera mitad del siglo XIX por el arquitecto Bruno Renard. En Bois-du-Luc se hallan numerosos edificios construidos en el periodo 1838-1909, así como una de las minas de carbón más antiguas de todo el continente europeo, cuya explotación se inició a finales del siglo XVII. A pesar de que Valonia contó con centenares de minas de carbón en el pasado, la mayoría de sus infraestructuras han desaparecido hoy en día. Sin embargo, las cuatro minas que componen este sitio del Patrimonio Mundial han conservado su integridad en muy gran medida.

Brief synthesis The Grand-Hornu, Bois-du-Luc, Bois du Cazier and Blegny-Mine sites represent the best preserved places of coal mining in Belgium, from the early 19th to the second half of the 20th centuries. The Walloon Coal Basin is one of the oldest, and most emblematic of the industrial revolution, on the European continent. The four sites include numerous technical and industrial remains, relating to both the surface and the underground coal mining industry, the industrial architecture associated with the mines, worker housing, mining town urban planning and the social and human values associated with their history, in particular the memory of the Bois du Cazier disaster (1956). Criterion (ii): Among the earliest and largest in Europe, the four Walloon coalmines are testimony to the early dissemination of the technical, social and urban innovations of the industrial revolution. They then played a major exemplary role on the technical and social levels through to recent times. Finally, they are one of the most important sites of interculturalism arising out of mass industry through the participation of workers from other regions of Belgium, Europe and later Africa. Criterion (iv): The ensemble of the four Walloon mining sites provides an eminent and complete example of the world of industrial mining in continental Europe, at various stages of the industrial revolution. It bears significant testimony to its industrial and technological components, its urban and architectural choices, and its social values, especially following the Bois-du-Cazier disaster (1956). Integrity The series’ components have been selected for the quality, diversity and wealth of the testimonies they provide. Each expresses an original and complementary dimension of the serial property’s overall value, and each has the necessary components demonstrating sufficient integrity for an intelligible expression of this overall value. Authenticity The authenticity of the individual components of the serial property varies somewhat depending on the component considered and depending on all the property’s sites, but it achieves a satisfactory level overall. The programmes announced for the renovation of certain components, such as the Grand-Hornu workers’ city, should favourably restore the conditions of authenticity for this property. Nonetheless, an overarching conservation plan would be welcomed to ensure the authenticity of this serial property is lastingly maintained. Protection and management requirements Overall, the protection measures for the sites are adequate. Guarantees have been provided for the sound management of the urban and rural buffer zones through local town planning or sector plans, implementing the general provisions of the Development Code for the environment of the listed monuments and sites. Starting from the addition of sites with separate management and conservation systems, the serial property has recently acquired a permanent overarching body that is operating effectively: the overarching Coordination Group. The scientific capacities of this group must be strengthened and the programmes and actions coordinated to achieve a level of management and conservation compliant with that of a property with recognised Outstanding Universal Value.
