What is the name of Poseidon's palace undersea?

Question

I've been trying to find out the name but I can't seem to find any website that discloses the name of the palace. Even if he had a handful of palaces, the name of only 1 would be better than nothing.

Answer 1

Atlantis

Answer 2

Sorry, no clue. I believe that there was only one of his own, though Amphritrite may have had one to herself. His was at Aegae (near the Peloponnesus), I believe.

As for Atlantis—just in case you didn't know, that was an island. I believe that Poseidon had his underwater palace BEFORE Atlantis sank underwater.

EDIT: I've been doing a  bit of research, but the palace really doesn't seem to have a name. I have figured out that Aegae is also spelled Aigai, though, and that there're still ruins of a royal palace in that area. But again, I can't find a name...
