There is a prominent river sewer in the Petersburg suburb. It is short (just about 300 meter long), but has an old part with stone walls and a brick dome, fantastic-looking pipe attachments and piles of trash. We have also found out that the water in this river is very clear and transparent, sponges grow on the bottom and there is a lot of fish from small to rather big. And the sewer is also populated with bats. So here are pictures by Mutabor (pic 1–6) and Rada (pic 7–17). The last two pictures are from the block of abandoned buildings located not far from the sewer.
