How do I get a temple in Age of Empires?

Unlike the campaign mode in Age of Empires II, which has five unrelated mini-campaigns, the Age of Mythology campaign mode offers one long campaign and one main story. The campaign story, titled Fall of the Trident, begins with the game's opening video. It shows a young Atlantean admiral and hero, Arkantos, as he explores an abandoned temple. Within the temple, he has brief glimpses of the goddess Athena that lead him to many engravings of warriors and several Olympian gods. As Arkantos touches each of the statues, he has strange visions of a fierce war between Kronos, the evil Titan Lord and its army of mythological creatures, and human warriors aided by Zeus. On his final vision, Arkantos sees how Kronos is sealed behind the huge gates of Tartarus, as the temple he is in begins to crumble. Athena makes a sign to Arkantos to escape, and he barely manages to, as a huge trident from Poseidon's statue nearly falls upon him.
