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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
