The Hall of Armor is a room containing Tony Stark's Iron Man armors, and consists of two different rooms in the Iron Man films. This is the place where Tony stores all his Iron Man suits, either defunct or active, when or after he works on and utilizes them.
Even though Tony's Malibu Mansion was destroyed in Iron Man 3, only the first Hall of Armor was destroyed, containing suits Mark I-VII, leaving the second, containing suits Mark VIII-XLII, still active. After the battle at the Roxxon Oil Rig, Tony Stark then activates the Clean Slate Protocol which results in the suits self-destructing, and displaying fireworks for Pepper Potts.
The Hall of armor is no longer used by Tony because of the Events of The Clean State Protocol, and because he now stores his suits in the Avengers Tower (and later the Avengers Facility).
The first Hall of Armor 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 the Mark I to Mark VI. The third and final version contained Mark I to Mark VII. The Mark I displayed was a reconstruction, and the Mark III displayed was not repaired, still bearing its battle damage.
Hall of Armor Extension
This is the second, extended section of the Hall of Armor. It's an extension hidden under the basement of his Malibu Mansion. It is directly connected to his garage, under the platform, which is just a few meters below from the Classic Hall of Armor.
The Hall of Armor has been upgraded to a wine cellar where the Iron Legion is held. The original armors (Marks I-VII) are in the original place that they were in Iron Man 2. When Tony's mansion is attacked, the visible Hall of Armor is destroyed along with the mansion. When the "House Party Protocol" was activated, Marks VIII-XLII were activated and flew to the Roxxon Oil Station to fight the Extremis soldiers.
The Hall of Armor was based on the place of the same name in the comics, and both designs are similar to each other.
