What is the name of the last human stronghold in The Matrix? The answer is Zion.
Zion is the last human city in the Matrix film series. It is not a surface metropolis but a vast underground settlement built in caverns deep beneath the ruined Earth. Humans who have been freed from the Matrix live there, organize resistance operations, and defend themselves against the machines.
The city is central to the sequels. In The Matrix Reloaded, the machines are preparing an assault on Zion, and the approaching Sentinel army creates the film’s countdown. The Architect later reveals that Zion and the rebellion have been incorporated into a repeating system of control: previous versions of the city were destroyed and rebuilt as part of the Matrix’s cycle.
In The Matrix Revolutions, Zion comes under direct attack. The human defenders survive only after Neo negotiates with the machines to stop Agent Smith, whose spread threatens both worlds. Zion is often confused with the Matrix’s fictional cities, such as Mega City; those are simulated locations, while Zion is the underground refuge of freed humans.
