Sometime after March 18, 2000, Henry Allen was incarcerated in Iron Heights after being wrongfully convicted for the murder of his wife. He was regularly visited by his son Barry Allen and friend Joe West many times while serving out his sentence.[2][3]

Oliver Queen and Laurel Lance both went to Iron Heights for an eighth grade field trip.[4]

In late 2012, Peter Declan was held in the prison, though he was later set free when he was acquitted of the charges placed on him.[5]

Later that same year, Oliver was held in the penitentiary after being accused of being the vigilante, The Hood, and he subsequently took a polygraph test in an attempt to prove his innocence. He was later set free when John Diggle masqueraded as The Hood while Oliver held a party at the Queen Mansion.[4]

In early 2013, Cyrus Vanch was formally released from Iron Heights Prison and was picked up by his associate Vivian.[1]

Moira Queen was held here when she was charged with committing mass murder during "The Undertaking".[6]

Many inmates including The Dollmaker and The Count escaped when The Undertaking hit Iron Heights.[7][8]

After the singularity over Central City was closed by the Flash and Firestorm in mid-2015, Iron Heights opened a separate wing which could hold incarcerated meta-humans.[9]

In 2016, Damien Darhk was held in Iron Heights, until with the help of Malcolm Merlyn and Andy Diggle escaped along with many other inmates including Michael Amar, Danny Brickwell, Noah Kuttler, and Cooper Seldon, during the chaos Darhk ended up killing Laurel Lance, The Black Canary.[10][11][12]

After Barry and Cisco beat the Rival, he was taken to Iron Heights and put in a cell in the meta-human wing. That night, Alchemy scolded him for his failure, and then Savitar entered the cell and killed him.[13][14]

In late 2017, Ramsey Deacon[15] and Becky Sharpe were both incarcerated in the meta-human wing.[16]

  • Iron Heights Prison is designed to hold the most dangerous criminals from Star City, Central City and Keystone City.
  • According to Cisco Ramon, there is no prison that can hold Barry Allen, this implies that Iron Heights Prison's power-dampening tech has no effect on Barry's powers; due to him spending six months inside the Speed Force.
    • Although he stated this while Barry was in with the "regular population" until he unknowingly outed himself to the Warden who then place Barry with the rest of the meta-humans and got the same power damper collars as them.
