Starting in 2010, Belgium rented 650 spots in Tilburg prison in the Netherlands, at a cost of 30 million euros per year. The government announced that the contract would end in 2016. Inmates from Wortel prison were transferred to Tilburg. The project was a failure, and in 2012 the Committee for the Prevention of Torture (CPT) criticised the climate of violence in the prison. The maintenance of family ties and reintegration into society proved difficult, and some French and Arabic-speaking prisoners found themselves isolated in an almost entirely Dutch-speaking environment.

The prison service is overseen by a Federal Public Service (FPS), with a territorial split along regional linguistic lines: there is a Dutch-speaking regional directorate in the north, and a French-speaking regional directorate in the south. Inmates are assigned based on the language they speak.

There is confusion surrounding the division of responsibilities between the federal government and federated entities.

There are three types of prison regimes, generally grouped within different wings of the same prison:

• Open regime: inmates can move freely within the prison (Hoogstraten, Ruiselede, Saint-Hubert and Wortel).
• Closed regime: inmates are confined to their cells, and allowed out for visiting hours, work and activities. The majority of prisons are under this regime.
• Semi-open regime: this combines features of the two other regimes (Marneffe and Merksplas).

Open and semi-open regimes are often seen as a favour granted to the prisoner, that can be withdrawn at any time.

As of 2016, the smallest prison, Tongres, had 25 cells and an average of 21 inmates. For that same year, the largest prison, Lantin, had 694 cells and an average of 905 inmates (latest published figures).

The older prisons are generally located within towns and cities. The newer prisons, built in the 1990s, are situated either on the outskirts of towns and cities or in rural areas - making access more difficult for staff, visitors, families and lawyers.

The facilities were built during several different periods:

• Eighteen prisons date from the 18th century
• Twelve prisons date from the 20th century
• Five were built in the 2000s
• Two forensic psychiatry centers date from the 1850s and the 1950s, respectively.

Since 2008, the prison facilities have been governed by a series of “Masterplans”. On 6 February 2017, the Minister of Justice announced “Masterplan III”, entailing the construction of a new prison (Vresse-sur-Semois), two halfway houses (Verviers and Léopolbourg) and the extension of three other establishments (Jamioulx, Ruiselde and Ypres). There are also plans for three new forensic psychiatry centers (Wavre, Alost and Paifve) and the renovation of Merkplas. This will increase the capacity of the prison system by several hundred places.

These new prisons, built through public-private partnerships (PPPs), have contemporary infrastructures, with separate toilet and shower blocks and a computer and telephone in each cell. They also represent a solution to endemic overpopulation. The Leuze prison in Hainaut, which opened in 2014 and has been at capacity since 2015, had an occupancy rate of 110% by October 2017.

The biggest ongoing project is a mega-prison in Haren, to the north of Brussels. This prison will house 1190 cells. There is no clear documentation explaining the reasons behind the construction of this prison. Successive governments have referred to a 2008 political agreement requiring them to build it, but there is no trace of such an agreement. The project will be carried out as a PPP, with a consortium of companies handling construction and ensuring maintenance for a period of 25 years. The government will begin paying rent as soon as the first inmate arrives. The estimated cost of the project is 3 billion euros over a period of 25 years.

Citizens’ groups and justice professionals are opposed to the project. All appeals have been rejected (June 2019), and the prison is set to open in 2022.
