In Sofia, in front of the NDK, there are two fountains. One of them is underground, at the metro level:
Now, I'm not saying that every single fountain in the world is expected to have a deeper meaning, but is one has been obviously designed with something in mind and it's nearly the weirder fountain I've seen in my traveling.
I tried asking to local residents, but surprisingly it seems that nobody ever thought about it. And funnily enough, while it seems (at least, that's what I've been told) I'm currently living in the house where the architect which could have designed it lived, the current owner of the house has no idea about the fountain too.
I obviously tried some Internet search, too, but came to nothing. So, can someone shed some light on this? What is the meaning, if any, of this humid piece of art?
