It provides an important and well preserved example of coal mining and its associated urban planning throughout the two centuries of intensive coal extraction from the end of the 18th century to the last quarter of the 20th century, through industrial methods involving a great many workers. This succession of landscapes resulting from the virtually mono-industry of coal extraction includes: physical and geographic components (slag heaps, farmland, mining subsidence ponds and woods), a mining industrial heritage (pit heads, residual industrial buildings and headgear), vestiges of transport equipment, the so-called ’cavaliers’, (canals, railways, conveyors), worker housing and characteristic urban planning (mining villages, garden cities, detached housing estates and tenement buildings), monumental and architectural components testifying to community life (churches, schools, managers’ châteaux, company head offices, worker union premises, stations, town halls, hospitals and clinics, community halls and sports facilities), and finally places of remembrance and celebration of the Basin’s history and its miners.
