Jaworzno, Poland, 10 April, 2022.
The former excavation site of the cement factory "Szczakowa", for some time one of the largest in the world, is now revitalized as the Park Grodek arboretum. The project, which has been going on for over ten years, is one of the examples of revitalisation of post-mining areas in the Silesian Province. Today, the terrace overlooking the artificial pond in one of the post-mining basins is the point from which tourists take the most photographs in the region every year. The flooded basin is a testimony to how quickly the level of groundwater, underground and above-ground water jumps in the region depending on the operation of mines, the beginning and end of mining. The artificial ponds were created because of a mistake made by one of the heavy industry outlets. Then the flume was built above the water level. For several years, due to the closure of the mines in Trzebinia, about thirty kilometers from Jaworzno, the water level has been recovering and flooding the previously built infrastructure.
