Earthdome was a large domed facility located in what used to be Geneva, Switzerland on Earth and commanded a stunning view of Lake Geneva. The elaborate facility functioned as the seat of government for the Earth Alliance.
From an architectural standpoint, the complex is designed with a golden reflective roof, which shimmers in the sunlight and can be seen from orbit when there is no cloud cover.
Constructed in 2132, Earthdome housed the Office of the President of the Earth Alliance, the Earth Senate, Earthforce Command and, until its dissolution, Psi Corps Headquarters. Other ancillary functions, such as xenobiological and weapons research, have significant facilities within Earthdome as well as several major alien embassies.
The Psi Corps HQ was totally destroyed by a bomb in the Telepath War.
