Today's pictures show historic grounds. This is where I grew up. It looks quite good now but it is a former mining area. The oldest coal mining area of Europe. It was in the 11th century that the coal reached the surface at Rolduc and mining was not very difficult. When the mine was exhausted they had to dig deeper and coal mines were established. During the 1960s most mines were closed and the grounds were developed for housing and recreation.
The road in this picture used to be a railroad for coal transport only. I had to cross it every day when going to school. A high wall and a barrier prevented us from entering the mining site.
These two pictures give you an impression of how it looks today. Neat houses and a lot of green.
Unfortunately I have no photo of how it was at hand. I must have a book with old postcards on my shelves but I could not find it. I hope I did not lend it to someone I don't remember.
