The Hall of Armors is a hall containing the armors of Tony Stark, and consists of two types in the Iron Man films. This is the place where Tony stores all his armors, either defunct or active, when or after he works and utilizes them.
Even though Tony's Malibu Mansion was destroyed in Iron Man 3, only the first Hall of Armors was destroyed, containing suits Mark I-VII, leaving the second, containing suits Mark VIII-XLII, still active, only after the battle at the Roxxon Oil Rig. Afterwards then, Tony Stark then orders a Clean Slate Protocol resulting J.A.R.V.I.S. to destroy the suits.
The first Hall of Armors was created by Tony after the events of the first Iron Man film. The first version only had four containment units for armors Mark I to Mark IV. The second upgraded version contained Mark I to Mark VI.The third and final version contained Mark I to Mark VII
This is the second part of the Hall of Armors. It is an extension that is hidden under the basement of his house. It is directly connected up to his garage, on the platform, which is just a few meters below from the Classic Hall of Armors.
The Hall of Armors has been upgraded to a wine cellar where the Iron Legion is held. The original armors (Marks I-VII) are at the original place that they were in Iron Man 2. When Tony's house is attacked, the visible Hall of Armors is destroyed along with his house. When the "House Party Protocol" was ordered, Marks VIII-41 turned on and flew to the Roxxon Oil Station to fight the Extremis soldiers.
