Belle Reve Penitentiary is a penal institution located in Belle Reve Parish. It is designed to hold supervillains and metahumans.
All inmates are required to wear inhibitor collars, with each one designed to restrain the wearer's specific meta-ability. The walls are strong enough to withstand even Superman, though are subceptible to other forms of assault.
The prison's psychiatrist, Hugo Strange, and inmate Icicle Sr., were working on a plan for the Light. It had two goals: disposing of warden Amanda Waller, and allowing the Riddler to escape. This would be masked by a destined-to-fail prison break, that involved the four ice villains making the walls brittle. Ultimately, the prison break was prevented by Superboy and Miss Martian (with unwitting help from Icicle Jr.), but the main goals had been accomplished. Riddler had escaped, and Hugo Strange was established as warden, and could now allow people that were of use to the Light to temporarily, and secretly, be put to use outside the prison.
In their search for Red Tornado and T.O. Morrow, the Team stopped by Belle Reve. Warden Strange could not deny them an audience with Morrow's chief competitor, Professor Ivo, because they had helped prevent a prison break. However, when he saw Zatanna was able to extract the desired information from him with ease, he made sure to have Ivo warn Morrow.
After Queen Perdita of Vlatava revoked Count Vertigo's immunity after a failed coup, he was sent to Belle Reve, and immediately became the subject of mockery from fellow inmates. As the coup involved a coordinated attack from five ice fortresses, Batman suspected the five ice villains in Belle Reve might have been involved. Strange showed him security footage, that showed each of them in their cells at the time of the attacks.
