's secret headquarters
Located within a mountain in the arctic circle,
Superman's Fortress of Solitude was created as a haven
for the Man of Steel. It houses many of the wonders that
he has collected over years of adventures, many of the
scientific wonders that he uses, and allows him to
spend time working on his various hobbies. It is a
combination museum, labratory, and rumpus room.
The door to the Fortress of Solitude is nearly
impervious to harm, opened by a huge key the size of
a Greyhound bus, that Superman uses to open it. When
the key is not being used, it is disguised as an
air route signaling device. The interior of the Fortress
contains such wonders as Superman's intergalactic
menagerie, the bottled City of Kandor, and the Phantom
Zone projector. The Fortress also contains Superman's
collection of Superman robots, that he uses to help
maintain his secret identity and which are highly advanced
though seemingly incapable of avoiding high power electric
lines, which were always used to defeat them.
Since the Crisis, Superman's fortress is underground
somewhere in Antarctica and contains wonders from his native
world of Krypton.
