The Hall of Justice
The Hall of Justice was constructed by the Justice League of America following a year after the destruction of the previous Justice League Watchtower, and located in Washington, D.C. and in the same location as the JSA and All-Star Squadron original headquarters. The Hall was designed by John Stewart and Wonder Woman, and financed by Batman and built from scratch by Superman.
The Hall was later appropriated by the United Nations as the headquarters for the new Justice League International. This causes public outrage, with many citizens taking offense to the idea of superheroes from foreign countries using an American landmark as their base of operations, and cause a few civilians to blow up the Hall while the JLI was away on a mission.
In the Void Earth continuity, instead of being erased from existence by the time stream as planned the Legacy Initiative kept the hall intact and in full working order. However, due to the high level security and also the disappearance of most of Earth's heroes it has been abandoned and left by the government in case the heroes do return. It is unsure what the Legacies will find once they go inside...
