The observatory is a protoss structure. It is required for the warping and upgrading of observers.

The protoss consider history to be of vital importance, and even during the Aeon of Strife scribes recorded the wars and their heroes for future reference. The observatory is a modern refinement of the ancient library, where data gathered by observers is recorded and cataloged.^[1]

DevelopmentEdit

During the StarCraft alpha, the observatory was known as the "beacon."^[2]

StarCraft IIEdit

The following section contains information from a previous version of StarCraft II which is no longer valid.

The observatory was a building in early builds of StarCraft II. It was canceled as of September 2008.^[3]

The observatory was used to enable the robotics facility to warp in observers and was also the center for their upgrades and upgrades for the phase prism.^[4]

It appears to have used the same model as the null circuit.
