The Justice League Watchtower was the headquarters of the Justice League of America. The Watchtower was constructed of promethium and used highly advanced Martian, Thanagarian, Kryptonian and Terran technology. The arrival of Orion and Big Barda added the technology of New Genesis and Apokolips to the systems within.
History
New Earth
The Watchtower was destroyed by Superboy-Prime[1] and superseded by the The Hall, based on Earth, and Satellite Watchtower in space.[2]
Earth 12
The Metro Tower in the future
In the Batman Beyond future, the Justice League Unlimited uses a Tower in Metropolis as their headquarters. The Tower was originally used by the first Justice League to replace the second Watchtower after the Project Cadmus crisis.[3][4]
