The Great Pyramid seen through the Guardian of Forever.
Pyramids were build by numerous Human Earth cultures as monuments, burial sites, and places of worship. The series of monumental burial chambers built for Egyptian kings of Earth, are among the oldest known, dating from the 27th Century BCE.
The Great Pyramid of Giza was the largest of the pyramids, and one of Earth's most notable landmarks. It had been observed by anthropologists, following proper time travel protocols, since 2769. Daniels showed temporal observers watching the pyramid's construction to Captain Archer in the temporal observatory. (ENT: "Cold Front")
After Archer restored a damaged timeline, the Pyramids could be seen in the timestream as the timeline realigned itself. (ENT: "Storm Front, Part II")
The Great Pyramid was also among the images displayed by the Guardian of Forever. (TOS: "The City on the Edge of Forever")
- Pyramid-like structures were also dominating the Ventax II skyline. (TNG: "Devil's Due")
