The opening comes as Costa Rica grapples with near-record homicide levels driven by increased fighting between criminal groups over drug routes. The country recorded 905 homicides in 2023, followed by 876 in 2024 and 873 in 2025.
"The CACCO will force criminals to face a new model – a tough-on-crime model. Costa Rica will become a global benchmark for prison security," Fernandez said during the inauguration ceremony.
First transfers to the facility are scheduled for the end of October. Justice Minister Gabriel Aguilar said the prison will help the government reassert control over the prison system and diminish infiltration by organised crime.
Across the region, other leaders are pursuing similar strategies. Peruvian President Keiko Fujimori, who took office in July, has announced plans to tour El Salvador's Terrorism Confinement Centre (CECOT), which can hold about 40,000 people, in anticipation of building a comparable facility. In Colombia, newly elected President Abelardo de la Espriella, who took office in August, campaigned on a pledge to construct 10 mega-prisons. In Brazil, right-wing Senator Flavio Bolsonaro has advanced to the final round of the presidential election with a platform that includes building five mega-prisons, citing the Salvadoran model.
While the crackdowns have proven popular, critics warn they often weaken key civil liberties. In El Salvador, the approach has involved mass arrests and the suspension of basic rights.
