Do underwater cities exist?

I would like to think so because I'm sure we haven't discovered every single part of the ocean and there's probably places way deeper that we don't even know of with other sorts of species.

Hell yeah! Underwater cities do exist. Like, have you heard of the ice wall? Yeah, that's the reason why we don't hear about Atlantis. But don't tell nobody I told you that! But, still exists man.

Hmm... maybe.

I don't know if all cities exist but it could be harder

Underwater cities Well, you know the world is supposed to be underneath of a firmament dome and over top of that firmament dome is the water remember that cartoon called the snorks It's about um It's about these little people that live in like this underwater world with a dome over it And they have like little snorkels for for some reason Yeah
