The Fortress of Solitude is Clark Kent's sanctuary in the Arctic,[1] which holds information about his dead planet Krypton and allows him to communicate with the A.I.'s of his late ancestors.[2]
Kara Danvers began using the Fortress as well after becoming Supergirl.[3] After Jor-El's AI was destroyed, Clark started using Tal-Rho's Fortress, where his mother's AI was.
Overview
The Fortress of Solitude is a vast sanctuary hidden somewhere in the Arctic. It appears to be built entirely from either crystal or ice. [1]
Inside, the compound houses a display of items Superman collected over the years from his adventures, as well as statues of his parents. Also present is some form of interactive computer database.[2][1]
History

Clark enters the Fortress of Solitude for the first time.
After the death of Jonathan Kent Sr., Clark came to the Fortress to learn about his abilities.[4]
At some point in the history of Earth-Prime, three rings that could absorb and emit Kryptonite radiation[5] were stored in Fortress. The Jarhanpurian named Rama Khan claims that they were his and were stolen from him long ago.[6]
At some point, Superman was exposed to so much Kryptonite that he needed to go to the Fortress to be healed by having it burned from his system.[7]

Lois and Clark in the fortress.
Clark asked Lois to marry him in the Fortress.[8]
Some time after 2007, Clark checked to see if Jonathan had superhuman abilities after showing some natural talent for sports. The Fortress's tests said it was unlikely however.[8]
In January 2020, Kara Danvers kept a bottled Earth in the Fortress until she and her allies would find a way to restore the planet in the new multiverse.[3]
Angry that Kara planned to use Myriad after saying that it was forbidden, Lena Luthor was teleported to the Fortress. Unbeknownst to her, a Morae who worked for Leviathan traveled with her. As Kara and Lena argued about hypocrisy, the Morae agent opened the cage to a baby Sun-Eater.

Lex Luthor finds the Fortress.
Later, Lex Luthor noticed that he had access to Superman's Fortress of Solitude through the teleporter.[1] While inside the Fortress, Lex stole something for Leviathan to be used against Supergirl,[6] later revealed to be Rama Khan's rings.[5]
When Lex invaded the Fortress of Solitude, he took the solar hammer and used it to try to destroy the Fortress, but he was stopped by the Superfriends.[9]

Clark and Jordan in the Fortress.
Clark had brought Jordan to the Fortress after he manifested some abilities and wished to test for more information. However the A.I of Jor-El concluded that Jordan's powers were a result of brief flare ups and that his human DNA would limit him.[4]
Clark tells Lois that he is taking Jordan to the Fortress, when Jordan's powers flare uncontrollably.[10] The A.I. tells Clark that Jordan will feel pain until he learns to control his super hearing.[11]

Clark protects Jordan in the Fortress of Solitude.
Since Jordan's lungs were freezing due to second-hand exposure to the synthetic kryptonite of Project 7734, Clark brought Jordan to the Fortress to be healed. The Jor-El A.I. told Clark that it had to be burned from Jordan's system for him to heal.[7]
Kal-El went to the Fortress to talk to the Jor-El A.I. about the revelation that Tal-Rho is his maternal half-brother. As the two talked, Jor-El revealed that reversing the Eradicator was beyond his knowledge.[12] Tal-Rho followed Clark to the fortress and put him in a trance where he kept reliving his memories. When Clark woke up, Tal destroyed Jor-El's hologram.[13]
The Inverse World's Kal-El flew to the Fortress after fighting Superman, where he took off his armor after sustaining damage during the fight.[14] To protect his Inverse World counterpart from being killed by Mitch Anderson, Superman gave Anderson coordinates to the Fortress instead of Tal-Rho's fortress, where he actually was. Soldiers went to the Fortress and discovered the armor of Superman's counterpart, leading Anderson to conclude that they were working together.[15]

Behind the scenes
- The Fortress of Solitude in the comics is Superman's sanctuary located in the Arctic. It first appeared in Superman #17 (July, 1942), created by Jerry Siegel and John Sikela.
- The Fortress changes appearance in Superman & Lois, being more cave-like and malformed, rather the bright and more refined appearance in Supergirl. No in-universe explanation has been given as to why a second set was built, but it's more than likely due to restrictions caused by the COVID-19 pandemic.
- The coordinates of the Fortress that Superman gave to Mitch Anderson in "Anti-Hero" (76.2 N, 100.6 W) places the Fortress around Bathurst Island, Canada.
