The departure from coal in Poland results in the process of decommissioning the underground coal mines. These, based in the region of Upper Silesia, recently undergo a paradigm shift ‘from mining coal to mining water’, as the discharge of the groundwaters is crucial for underground security.

Rather than an obstacle, the discharged groundwaters, along with the post-mining infrastructure, can be treated as an asset for the systemic remediation of the post-mining territory. Thus, the preliminary research is structured around multiscalar remediation that considers the degraded environment, local society, and mindset. The subsequent design project entails a systemic intervention at the intersection of land- and built forms aimed at the multilayered remediation where water constitutes both the axis and the core of the unfinished terraforming laboratory.
