Korydallos Prison is a high-security facility located in Korydallos, a suburb of Athens, Greece. It was established in 1969 and is known for housing some of the country's most dangerous criminals, including members of organized crime and political prisoners. The prison has a capacity of around 1,200 inmates and is designed to ensure strict security measures. The prison has faced criticism over the years for overcrowding and poor living conditions. In response, the Greek government has implemented reforms to improve inmate welfare and reduce the prison population. Despite these efforts, Korydallos Prison remains a significant part of Greece's criminal justice system.
