The Temple of Hopes
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Temple of Five is a temple built on the Algae planet by the Thirteenth Tribe. The Sacred Scrolls say that the five pillars inside the temple were fashioned after the five priests devoted to "The One Whose Name Cannot Be [Told(?)]." Within the temple lies the Eye of Jupiter, an artifact that supposed points the way to Earth.
The temple is rediscovered by Galen Tyrol, who wanders off from the base camp of the Fleet's algae harvesting mission and finds himself at the temple's entrance in a nearby mountain side (The Eye of Jupiter).
