Niche of one sandstone underground place at Prague
With arrival of 20th century were underground sandstone mining chambers of Prague slowly abandoned. Local snadstone mining died out and even coal mining was never really profitable at Prague. Some places were used as shelters during World War II, but most of underground objects were forgotten. Some were filled up, others were visited only by people on the edge of society, local nosy parkers and sporadically by qualified speciallists. An illegal dumping still neighbors these hewn chambers, but most of the underground remains relatively clean and also photogenic thanks to it's whitish color.
