Russian penal colonies are the main form of incarceration in Russia, holding most of the country’s roughly 282,000 inmates across more than 640 facilities that stretch from western Russia to the Arctic and Siberia.1 Unlike prisons in most countries, where inmates live in cells, colonies house people in large open barracks where dozens or even hundreds sleep in a single room. The design traces directly to the Soviet labor camp system, and the physical infrastructure, daily routines, and institutional culture remain recognizably linked to that origin. The result functions less like a collection of buildings and more like a self-contained industrial settlement, where work, punishment, and a rigid informal social order define daily life.
The Federal Penitentiary Service, known by its Russian acronym FSIN, runs the system. It oversees convicted inmates, pretrial detainees, probationers, and prisoner transport. Although the agency has a formal mandate to rehabilitate, observers note that the absence of a fundamental post-Soviet overhaul means its institutional norms remain rooted in Gulag-era practice.
Colonies, Prisons, and Pretrial Centers
The Russian penal system has four kinds of facilities: pretrial detention centers (SIZOs), corrective colonies, prisons, and juvenile colonies. Corrective colonies dominate, with 642 in operation compared to just eight facilities classified as “prisons.” The system also runs around 204 SIZOs and 18 juvenile colonies. As of May 2026, the total incarcerated population stood at roughly 282,000, down significantly over two decades but still high by European standards.
The distinction between a colony and a prison matters. Colonies are built around the barracks model, with large dormitory-style buildings inside perimeter fencing and industrial work zones. Prisons use a cell-based system closer to the Western model. Only the most dangerous or persistently disruptive inmates get transferred to one of the eight prisons, sometimes called “kryty” in prison slang. Being sent to a prison is considered harsher than serving in a colony because the isolation and restriction of movement are far more severe.
The Four Regime Levels
Within the corrective colony system, facilities operate under one of four escalating security regimes. The regime assigned to an inmate depends on the severity of their crime, their criminal history, and their gender.
Settlement Colonies
Settlement colonies are the least restrictive. Inmates convicted of negligent or minor offenses serve their time here, often in hostel-style housing rather than barracks. They move relatively freely within the grounds, wear civilian clothing, and in some cases live with their families nearby under supervision. Passes to leave the colony are common. These facilities function more like supervised residential zones than traditional prisons.
Ordinary Regime Colonies
Ordinary regime colonies hold the largest share of the incarcerated population: men convicted of serious crimes for the first time, and women convicted of virtually any offense. Security tightens substantially. Inmates live in barracks that can hold up to 150 beds in a single room. Movement is monitored, and inmates cannot freely roam the facility. The barracks environment produces constant communal living with no privacy, which breeds its own set of social dynamics and conflicts.
Strict Regime Colonies
Strict regime colonies hold men convicted of particularly serious crimes or those with prior convictions. Open barracks give way to locked cells typically holding 20 to 50 inmates. Inspections are more frequent, access to common areas is curtailed, and physical barriers between zones are more robust. The step up from ordinary to strict regime brings a meaningful change in daily experience, with far less freedom of movement and heavier surveillance.
Special Regime Colonies
Special regime colonies sit at the top of the severity ladder, holding inmates serving life sentences and those deemed the highest security risk. Housing is cell-based, surveillance is constant, and isolation from the general population is the norm for at least the initial portion of a sentence. Facilities like IK-6 near Melekhovo and the Arctic colony IK-3, known as “Polar Wolf,” have drawn international attention. IK-3, where opposition figure Alexei Navalny spent his final months before dying in February 2024, is known for collective punishment practices, winter temperatures dropping to minus 20°C, and a culture in which one inmate’s infraction can force the entire unit to stand outside without coats.
Mandatory Labor and the Daily Schedule
Work is not optional. The Penal Enforcement Code requires all able-bodied inmates to perform whatever labor the administration assigns. Colonies function as industrial sites producing garments, furniture, metal goods, and consumer products. The stated purpose is vocational training and discipline, though in practice the work typically involves repetitive manual tasks with limited training value.
A typical day starts at 6:00 AM. Inmates dress, line up, and perform a half-hour exercise period. After a morning headcount and breakfast, the workday begins and generally runs a full eight-hour shift. A midday break allows for lunch and cleaning. After the shift ends, a second exercise period and dinner follow. Evening hours bring administrative briefings and limited personal time before a final headcount and a 10:00 PM curfew. Every hour is mapped onto a rigid timetable, and deviations trigger consequences.
Russia’s Labor Code sets general workplace safety standards, including the right to refuse dangerous work and requirements for professional training. Whether those protections are enforced inside penal colonies is another question. The FSIN runs its industrial zones with minimal independent oversight, and workplace injury data from inside the system is not reliably available.
The Informal Inmate Hierarchy
A rigid, unwritten caste system operates in parallel with official rules, and in many colonies it exerts more influence over daily life than the administration does.
At the top sit the “vory v zakone,” or thieves-in-law, a small class of elite criminals who control significant portions of the underworld inside and outside prison walls. Just below them are the “blatnye,” professional criminals who enforce the informal code within the colony. These two groups set the social rules and resolve disputes among inmates.
The vast majority of inmates fall into the “muzhiki” category: ordinary people serving a single sentence who keep their heads down, do their work, and stay out of internal power struggles. They do not cooperate with the administration, and they do not take part in the criminal power structure.
A separate and stigmatized category includes those who do cooperate with prison officials, called “kozly” (goats) or “activists.” They may hold administrative posts within the colony, but their cooperation makes them social outcasts among the general population. At the very bottom are the “opushchennye,” inmates forcibly expelled from normal social life. They eat from separate dishes, sleep near the toilets, and are untouchable in the literal sense: any physical contact with them or their belongings risks dragging another inmate down to the same status. This hierarchy is not a relic. It operates in enforced form across the colony system and shapes everything from where an inmate sleeps to whether they survive their sentence.
ShIZO and Escalating Punishment
Colony administrations maintain order through a set of escalating punishments. The most common and most feared is the ShIZO, a punishment isolation cell where inmates can be placed for up to 15 days per infraction. In practice, that legal maximum means very little. Officials routinely cite a new violation the moment an inmate’s 15 days expire, chaining multiple ShIZO terms back to back for months at a time. Navalny spent nearly 300 days in solitary confinement across his time in the colony system, much of it in ShIZO cells.
Conditions are deliberately punishing. Inmates describe concrete rooms with no natural light, extreme temperatures, constant artificial lighting that prevents sleep, and rations limited to basic prison food. The bed folds against the wall during the day and can only be lowered at designated sleeping hours. Visitation, parcels, and store purchases are all prohibited. The infractions that trigger ShIZO placement can be genuinely minor: failing to place hands behind the back, addressing a guard without using the proper form, or not clearing leaves in a yard.
Beyond ShIZO, inmates who repeatedly break rules face transfer to PKT, or cell-type rooms, where they can be held for up to six months under heightened supervision. The most persistent violators get moved to EPKT, unified cell-type rooms that function as what inmates call “a prison within a prison.” These are separate locked areas within the colony with their own internal rules and near-total isolation from the general population. Each step strips away more rights and more contact with the outside world.
Visits, Calls, and Parcels
The number of visits an inmate receives each year depends entirely on which regime they serve under. Settlement colony inmates can see family relatively often, while those under special regime face severe restrictions. Life-sentence prisoners in special regime colonies are entitled to just two short visits per year, each lasting four hours, conducted through a glass partition with a guard within earshot. That restriction applies automatically based on the sentence, regardless of behavior, and lasts a minimum of ten years before any possibility of relaxation. The European Court of Human Rights ruled in Khoroshenko v. Russia that this blanket restriction violated the right to family life, though the ruling carries no enforcement weight after Russia’s departure from the Council of Europe.
Long-term visits, available under less restrictive regimes, let family members stay with the inmate for up to three days in small apartments on the colony grounds. These count as a significant privilege and serve as a powerful incentive for compliance.
Phone calls are capped at 15 minutes each and require prior written approval from the administration, including details about who the inmate is calling and in what language. The number of calls is theoretically unlimited, but colonies with limited phone infrastructure may restrict inmates to as few as six per year. Inmates under strict regime or disciplinary sanction may only receive phone access in exceptional circumstances.
Parcels are subject to weight limits and frequency caps that vary by regime. Under ordinary regime, inmates may receive up to 12 parcels per year weighing up to 20 kilograms each, plus 12 smaller posted packages of up to 5 kilograms. Under the strictest regimes, that drops to one parcel and one small package per year. All incoming mail and parcels are inspected. An electronic messaging service called FSIN-Pismo lets people send digital letters and photos to inmates, but all messages pass through administrative censorship and, if approved, are printed and delivered within a few days.
Women in the Colony System
Women make up a small fraction of the Russian prison population, but the system was designed around men. Women’s colonies share the same barracks model as men’s facilities, with dorms housing as many as 60 women in bunk beds with half a shared nightstand per person. Women receive a single designated “wash day” per week for showers. Solitude is not available at any point.
Healthcare disparities are striking. The system maintains 59 colonies with tuberculosis treatment programs for men and just one for women. Substance abuse treatment programs are similarly tilted toward male inmates. Women who give birth in custody are typically separated from their children, who are housed in special nursery units on colony grounds; only two colonies in the country provide joint accommodation for mothers and infants. Reintegration programs tailored to women leaving the system are essentially nonexistent.
Abuse, Deaths, and the Collapse of Oversight
Reports of systematic abuse are not isolated incidents. The U.S. State Department’s 2024 human rights report documents accounts of authorities in prison colonies systematically torturing inmates, including cases resulting in death or suicide. The most common methods include electric shocks, suffocation, and pressure on joints and ligaments, chosen because they leave fewer visible marks.
The scale became harder to deny in 2021, when the Russian human rights group Gulagu.net released over 1,000 videos from inside facilities showing inmates being beaten and sexually assaulted. The footage, sourced primarily from a prison in Saratov, led to the firing of five senior prison officials and the resignation of the regional FSIN head. Russia’s Investigative Committee opened inquiries into sexual violence and abuse of authority, but systemic change did not follow. The State Department report describes impunity within the security forces as a “significant problem,” noting that authorities routinely deny requests for independent investigation and run disinformation campaigns to deflect allegations.
The federal prison system’s own estimates indicate between 1,400 and 2,000 deaths occur annually within the system. Medical neglect is a recurring factor. In Navalny’s case, he was denied access to a dentist for 18 months, developed serious back problems that left him unable to walk properly, and was housed with an inmate who had tuberculosis. More than 500 Russian doctors signed an open letter demanding he be seen by a civilian physician. His treatment did not change.
For years, the European Court of Human Rights served as the primary external check on Russian prison conditions. It issued landmark rulings against Russia, including findings of inhuman detention conditions due to overcrowding and poor sanitation in Kalashnikov v. Russia and structural failures in the pretrial detention system in Ananyev v. Russia, which ordered Russia to improve physical conditions, establish maximum capacity limits, and create an effective complaint mechanism for inmates.
That external pressure ended on September 16, 2022, when Russia formally ceased to be a party to the European Convention on Human Rights following its expulsion from the Council of Europe earlier that year over the invasion of Ukraine. ECHR rulings issued after that date carry no binding force against Russia, and the court no longer accepts new applications concerning Russian detention conditions.
Domestically, Public Monitoring Commissions established under Federal Law No. 76-FZ of 2008 are the formal mechanism for civilian oversight. On paper, these commissions can inspect colonies and interview inmates. In practice, they lack unimpeded access, their members have no legal immunity, and their independence from the agencies they are supposed to monitor is severely compromised. With the ECHR gone and domestic oversight effectively neutralized, no credible independent body currently has the power to hold the FSIN accountable for conditions inside its facilities.
