The Temple of the Gods is a circular open chamber made in honor of the three brothers, containing the statues of Poseidon, Zeus, and Hades (in that order).
God of War: Chains of Olympus
In Tartarus, after Kratos escaped from his imprisonment and fought his way out of the prisons and various enemies, he climbed his way up to a temple built in honor of the gods. There he pulled the statues of Poseidon and Hades to reveal a lever, which rotated the statue of Zeus and opened a path that led to the crypt.
Trivia
- Poseidon's statue can be smashed to reveal a chest containing Red and Blue Orbs.
