Kazimierz-Juliusz hard coal mine

Kazimierz-Juliusz is a closed hard coal mine in Sosnowiec with underground shafts that extended deep into the Upper Silesian Coal Basin. The site displays the infrastructure of a modern mining operation with multiple entrances and extraction facilities.

The mine began operations in 1884 and extracted coal for more than 130 years in this region. Its closure in 2016 marked the end of hard coal mining in the Dąbrowa Basin and signaled the region's transition away from coal production.

The site reflects the work of miners who operated here for generations and shaped the region's industrial culture. The structures show how important this labor was to local communities and how it shaped everyday life for families in the area.

The site is a technical monument under continuous geological monitoring and is not freely accessible to visitors. You should check ahead about whether guided tours or special visits are available.

The site features a specialized network of seismic sensors that record ground movements and vibrations from the ongoing mine flooding process. This scientific monitoring makes the location an example of how abandoned mines are managed and studied today.
