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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
