Where does Poseidon live?

In Greek mythology, Poseidon lives in an underwater palace in the sea instead of on Mt. Olympus with the other gods. Poseidon is god of the sea, horses and earthquakes.

Originally, the gods of Olympia competed for control of the world's territories. Poseidon won control of the seas, Zeus of the sky and Hades of the underworld. At his palace under the sea, Poseidon has white horses and a golden chariot. As he is also god of earthquakes and creatures that make the earth shake, such as horses, his quick temper often causes earthquakes. Poseidon is often jealous of the all-powerful Zeus and seeks revenge against those who wrong him by sending the sea after them.
