Blegny-Mine is one of the four major coal mines in Wallonia, a recognised UNESCO world heritage site. It is an authentic coal mine with underground galleries accessible for the visitors through the original shaft.
In Blegny, the coalworking started in the 16th century under the impulse of the Monks of Val-Dieu, owners of the coal area. The first granting, Trembleur, was allowed to Gaspar Corbesier in 1799. This marked the beginning of the industrial coal working. Corbesier's descendants get the granting Argenteau which is settled near Trembleur. both grantings were put together in 1883 and totalise 2,171 acres. In 1887 the activities stopped for 30 years and the company is put into liquidation.
In 1919, a new company was created and the family Ausselet grounded the 'Company of Argenteau'. the production grew rapidly and reached 84.000 tons in 1931. During the Second World War, the tour of the pit 1 and the coal-washing building were destroyed. Coal extraction still remained by using the 'Pit Mary' but consequently with a lower rate of production. From 1942 till 1948 the pit and the wah-and-sorting building were reconstructed.
The production continued and reached 232.000 tons for 680 mineworkers. In 1975, the Industrial ans Social Ministerial Committee of Belgium stopped state grants to coal mines. In the region of Liège, the coal mines were closed one by one. The latest one 'Argenteau-trembleur' closed on March 31st, 1980.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
