A look inside one of the world’s most feared prisons, where the lights never go out, inmates are permitted just a single item in their cell, and some are serving sentences that stretch beyond 700 years.
El Salvador’s CECOT facility holds around 40,000 inmates described as some of the most dangerous criminals on the planet, including convicted murderers.
During an interview, one prisoner claimed he had killed 30 people and felt ‘no remorse’, adding that he would do it again if he were ever released — something the system is designed to prevent.
Prisoners are confined in shared units that house roughly 80 to 156 people at once. They sleep on tiered metal bunks and are not provided with mattresses, pillows, or bedding.
Spanning an area comparable to 32 soccer pitches, the complex is presented as the largest prison in the world.
Despite housing notorious and violent gang figures, the regime is built around strict compliance, with authorities insisting that no one dares test the rules.

Prison director Belarmino García has said anyone who even considers breaking the rules can be punished by being placed in a sealed concrete space with no light for as long as 30 days.
Inside the cells, the only permitted possession is a bible. Beyond that, inmates are barred from screens, books, newspapers, and other distractions, while conversation is tightly restricted.
A new Channel 5 documentary that goes inside CECOT — formally called the Terrorism Confinement Center — details daily life in the institution, amid criticism that the conditions may breach international human-rights standards.
Titled Richard Madeley on Murder Row, the programme shows an intense routine in which inmates remain locked in their cells for 23 and a half hours per day, with just 30 minutes set aside for exercise.

García also said the lights stay on around the clock, explaining it allows him to ‘see what they are doing’.
CECOT was constructed as part of President Nayib Bukele’s 2023 crackdown on gang violence and is used primarily to hold alleged members of MS-13 and Barrio 18.
According to García, certain gang-linked tattoos can be enough to get someone sent to CECOT indefinitely, simply due to the identifiable markings.
He has previously labelled the prison ‘hell’, and the documentary reports that meals are repetitive, with inmates eating beans and rice twice a day.
Richard Madeley on Murder Row is now available to stream on Channel 5.
