Fortress of Solitude
The Fortress of Solitude
The impenetrable fortress, carved out of a mountainside amidst the barren Arctic wastes, and serving as both as a retreat and a headquarters, it is Superman's secret sanctuary. Far from civilization with an extraordinary trophy room, it houses the hard won memorabilia of more than a thousand adventures, a workshop and super-laboratory, where Superman labors in search of an antidote to kryptonite and performs other experiments and the gymnasium and recreation facilities where Superman exercises, relaxes, and indulges in a variety of super hobbies. It also houses an interplanetary zoo, containing live species of wildlife from distant planets, as well as special rooms and memorials in honor of Superman's parents, foster parents, and closest friends. The Fortress of Solitude is also home to the amazing bottle city of Kandor, a city of the planet Krypton that was reduced to microscopic size and stolen by the space villain Brainiac sometime prior to the death of Krypton.
In the Fortress of Solitude, there are also special monitors for communicating with Kandor, the undersea realm of Atlantis, the Phantom Zone, countless distant planets, and alien dimensions. The Fortress of Solitude also houses an incredible collection of Superman-robots, other special equipment, numerous other rooms, exhibits, weapons, machines, and scientific devices. Indeed, since the invasion of the Fortress of Solitude by an outsider could result in the placing of these devices in the hands of evildoers, as well as endanger Superman's secret identity, the exact location of the Fortress of Solitude remains one of the world's most closely guarded secrets.
