Palmasola -

" Centro de Rehabilitación Santa Cruz "Palmasola" is a maximum security prison in Santa Cruz, Bolivia. It is Bolivia's largest prison and holds about 3,500 prisoners. Like many prisons in Latin America, guards exhibit minimal control over what happens within the prison, leading it to being described as a "prison town". Guards instead concentrate only on securing the perimeter of the facility. According to former inmates, almost anything can be obtained in the prison, and businesses operate inside the prison to supply weapons and drugs. Prisoners of Palmasola have created an organization called the Disciplina Interna to oversee some affairs. - Wikipedia"
