Major Mining Sites of Wallonia

The Major Mining Sites of Wallonia is a UNESCO World Heritage Site comprising four sites in Wallonia in southern Belgium associated with the Belgian coal mining industry of the 19th and 20th centuries.[1] The four sites of the grouping, situated in the French-speaking Hainaut Province and Liège Province, comprise Grand-Hornu, the Bois-du-Luc, the Bois du Cazier and Blegny-Mine.

Location of Major Mining Sites of Wallonia in Belgium


The site was recognized by the UNESCO commission in 2012 and is officially described:

The four sites of the property form a strip that is 170km long by 3 to 15 km, crossing Belgium from east to west. It consists of the best-preserved 19th- and 20th-century coal mining sites of the country. It features early examples of the utopian architecture from the early periods of the industrial era in Europe within a highly integrated, industrial and urban ensemble, notably the Grand-Hornu colliery and workers’ city designed by Bruno Renard in the first half of the 19th century. Bois-du-Luc includes numerous buildings erected from 1838 to 1909 and one of Europe’s oldest collieries dating back to the end of the 17th century. While the Walloon region had hundreds of collieries, most have lost their infrastructure, while the four components of the listed site retain a high measure of integrity.


During the Industrial Revolution in the 19th century, mining and the heavy industry that relied on coal formed a major part of Belgium's economy. Most of this mining and industry took place in the sillon industriel ("industrial valley" in French), a strip of land running across the country where many of the largest cities in Wallonia are located. The named locations of this World Heritage Site are all situated in or near the area of the sillon industriel.

The mining sector in Belgium declined during the 20th century during deindustrialization and today the four mines listed are no longer operational. Today, they are each open to visitors as museums and are an important part of Belgian industrial heritage.
