Sometimes during my walks I see constructions that I have no idea of their purpose. That puzzles me, if I have time, especially that they are in a strange places. Like in this case, the middle of a small square in the middle of the city. Ventilation? Does that mean there are underground tunnels? Anyway nice exercise for the imagination 🙂
That is really interesting,Sometimes these mysterious structures make you wonder what is going on beneath the surface. Great observation.
Thank you
