Prisons in Switzerland are operated by theSwiss cantons, which are responsible forlaw enforcement in Switzerland. As of 2008, Switzerland has 124prisons according to the Catalogue of Correctional Institutions (Katalog der Einrichtungen des Freiheitsentzuges) compiled by theFederal Statistical Office; other statistics, which account for various institutions being administratively associated with each other, report 117 prisons.^[1] Swiss prisons have a capacity of up to 6,736 detainees total (amounting to 89 detention places per 100,000 inhabitants),^[2] including up to 477 women and 105 minors. The detainees are housed in 4,531 single cells, 1,044 cells for multiple persons, 172 security cells, 200 disciplinary cells and 50 infirmary cells.^[1]

In 2008, Swiss prisons housed 5,780 detainees (77 detainees per 100,000 inhabitants), of which 5.8% were female, 1.2% minors and 69.7% non-Swiss nationals.^[2] Half of all detainees were serving prison sentences, a quarter were in pre-trial detention, six percent were detained for expulsion and extradition and three percent were reported as being in "protective custody and custody for other reasons".^[2] Additionally, in 2006, 5,333 persons served a prison sentence in the form ofcommunity work orders, and 114 served their sentence in the form ofelectronic monitoring house arrest.^[3]

in 2017, Prisoners that were locked up added up to about 6,900, while its maximum capacity is at about 7,500. The prison rate for Switzerland as of 2017 is up to 81 per 100,000. These numbers seemed to have slightly increased since 2008.^[4]

According to a 2006U.S. government report, Swiss prison conditions generally meet international standards, butprison overcrowding is a problem, particularly in the cantons ofGeneva,Zürich andBern. The report cites a 2005 Swiss government report stating that one-third of the country's detention centers were at or above their designated capacity, and nine were overcrowded by 20 percent or more.^[5] Overcrowding to 200% of capacity caused a mutiny at Geneva'sChamp-Dollon prison in 2006.^[6]

Since the 1950s, correctional policy, prison construction, and operation is coordinated in organizations set up through regional agreements between several cantons (Strafvollzugskonkordate). As of 2009, these are:^[7]

• Northwest and Central Switzerland Sentence Execution Agreement (Strafvollzugskonkordat der Nordwest- und Innerschweiz) consisting ofUri,Schwyz,Obwalden,Nidwalden,Luzern,Zug,Bern,Solothurn,Basel-Stadt,Basel-Landschaft andAargau
• Eastern Switzerland Sentence Execution Agreement (Strafvollzugskonkordat der Ostschweiz) consisting ofAppenzell Innerrhoden,Appenzell Ausserrhoden,Glarus,Graubünden,Schaffhausen,St. Gallen,Thurgau andZürich
• Latin Switzerland Sentence Execution Agreement (Strafvollzugskonkordat der lateinischen Schweiz) consisting ofFribourg,Geneva,Jura,Neuchâtel,Vaud,Valais andTicino

Training of prison staff is the responsibility of the jointSwiss Prison Staff Training Centre (French:Centre suisse de formation pour le personnel pénitentiaire, German:Schweizerisches Ausbildungszentrum für das Strafvollzugspersonal, Italian:Centro svizzero di formazione per il personale dei penitenziari) inFribourg.^[8]

Prisons inantiquity were primitive detention facilities consisting ofdungeons andoubliettes used to secure individuals duringcriminal proceedings or to compeldebt payment. During theMiddle Ages, prisons served similar functions, often detaining individuals who had failed to payfines. These facilities were typically dungeons or oubliettes constructed incastlebasements.Monasteries were sometimes equipped within-pace cells forreligious personnel subjected todisciplinary measures.^[9]

In the ninth century, theCarolingians established prisons for confining members of the upper class who had committedoffenses.Italianstatutes from the thirteenth century document the existence of prisons serving forcriminal detention. According to thecode of Lübeck (1240),imprisonment for a determined duration could constitute asanction. TheConstitutio Criminalis Carolina, introduced in 1532, which provided for limited-term incarcerations for certainoffenses andlife imprisonment fordeathsentences commuted bypardon, made prison a standard instrument ofpunishment execution. Most commonly, prisoners were confined in underground dungeons or fortified towers, where detainees, oftenchained and deprived of rights, languished under precarious and extremely unsanitary conditions.^[9]

In rural regions of theConfederation, there were no proper prisons until the eighteenth century, only simple facilities that occasionally served this purpose.Cities were better equipped withtowers (the Prisons Tower inBern from 1405),fortresses (Aarburg), and formerconvents. Imprisonment, applied primarily asretaliation or exceptionalpreventive measure, systematically presented characteristics of severe and prolongedcorporal punishment. Its purpose was not to improve detainees but only to punish them by inflicting physical and psychological suffering. High-ranking prisoners sometimes benefited from improved detention conditions.^[9]

InEngland, theHouse of Correction ofBridewell was created in 1557 to combatbegging andvagrancy. On thecontinent, the first reformatory for maledelinquents andbeggars opened inAmsterdam in 1595. InGerman-speaking countries,educational currents at work during the earlyabsolutist period favored the use of imprisonment with pedagogical aims in the seventeenth century. Through hard labor and strict discipline, detainees were expected to repent while being useful to the community, leading to their improvement. Simultaneously, imprisonment aimed to deter potentialcriminals, especially beggars tempted bycriminal behavior. Those condemned toforced labor, placed in disciplinary houses (Schellenwerk), had to perform public utility work all day (road maintenance, ditch restoration). They spent nights in cells. In the seventeenth century, severalcantons established such houses:Bern in 1614/1615,Basel andFribourg in 1617,Zurich in 1630 (in the formerOetenbach convent from 1637),Geneva in 1631, andSt. Gallen in 1661.^[9]

The most severe punishment in theHelvetic Republic's 1799Penal Code wasirons with forced labor. The code also provided for detention without irons, either insolitary confinement or collective cells where detainees could choose their work. The Helvetic Republic operated central prisons inBasel,Zurich,Bern,Solothurn,Lucerne,Fribourg, andBaden. Additional facilities were needed as the Penal Code's implementation caused a massive increase in prisoner numbers. Several execution regulations were enacted in 1800. Under theRestoration, several cantons (Lucerne,Thurgau,Vaud,Solothurn,Bern) adopted these regulations with modifications, but collaboration between Swiss prisons disappeared.^[9]

Aargau,St. Gallen,Basel,Ticino,Schaffhausen, andZurich in 1836 created their ownpenal codes, mostly inspired byAustrian andBavarian models that considered imprisonment the principal sanction. InCentral Switzerland cantons, which returned toAncien Régimepenal norms after the Helvetic period, imprisonment sentences maintained priority alongsidecorporal punishment and thepillory.^[9]

InGeneva, wherecourts had applied theFrench Penal Code since 1810 and regularly pronounced imprisonment sentences, a modern cantonalpenitentiary emerged in 1825. Its principles (discipline, isolation, silence) resembled those of theNew York Auburn prison. In 1826,Lausanne acquired a modern penitentiary wherecriminal sentences andcorrectional measures were executed according to thesilent system. This system, which prohibited prisoner communication, was adopted in 1839 in modified form at the St. Jacques cantonal penitentiary inSt. Gallen. TheLenzburg penitentiary inAargau began operation in 1864, where sentences were served according to theprogressive Irish system (gradual improvement of detention conditions) combined withagricultural work in open settings. These modern prisons accommodated different types of sentences and had separate divisions forwomen.^[9]

TheBernese institution that received its first detainees in 1834,Lucerne prison, and other Central Swiss establishments practiced communal detention in converted former public buildings, such asUri's formerleper colony, requiring numerousguards. InZurich, the prison was housed in the formerDominican convent ofOetenbach (renovated in 1834). The sentence execution regime remained largely dependent on outdated forced labor traditions but was reformed under the influence ofConrad Melchior Hirzel, author of the essay "Über Zuchthäuser und ihre Verwandlung in Besserungshäuser" (1826). It was based on dominantChristian values of the time. Work was considered a means of disciplining detainees and leading them to live respectfully. They should not be humiliated but receive instruction andmoral edification. TheRegensdorf penitentiary received its first prisoners in 1901, where progressive methods aimed at reintegrating detainees of both sexes into society were introduced based on the 1903 sentence execution ordinance. Cantons intensified their collaboration from 1867, following the founding of the Swiss Society forPenitentiary Reform.^[9]

The evolution of the prison regime in the twentieth century was characterized by modulated sentence execution. Establishments were created forfirst-time offenders and others forrepeat offenders, open, semi-open, or closed establishments, and facilities for executing measures.Hindelbank has housed Switzerland's only women-only penitentiary since 1896. Between 1984 and 1994, annual incarcerations in sentence and measure execution establishments numbered approximately 10,700. After a temporary decline (approximately 5,400 in 2001), numbers increased again (approximately 7,800 in 2007). Traditional incarceration was increasingly replaced by new forms of sentence execution:semi-detention,community service, andelectronically supervised sentence execution. The proportion of these new execution forms increased from 30% in 1984 to 49% in 2007. Since the revised Penal Code's implementation (2007),monetary penalties (day-fines) could replace short imprisonment sentences, helping reduce prison overcrowding.^[9]

Historically, prisons were housed in multipurpose buildings rather than purpose-built facilities. Early prison precursors were often integrated into larger institutional complexes, particularly hospitals. The city ofGeneva constructed a general hospital from 1707 to 1713 (which became acourthouse in 1857), with a "discipline building" situated slightly set back, which returned to service in 1868 under the nameprison Saint-Antoine. Similarly, the grand hospital ofBern (today the citizens' hospital) built from 1734 to 1742 combined anasylum,orphanage, andhouse of correction (Spinnstube). The sober,barracks-like buildings of disciplinary houses (Schellenwerke) also prefigured carceral architecture, as reflected in the nickname that became the official name of theBasel prison opened in 1864:Schällemätteli.^[9]

This architectural evolution accelerated during the nineteenth century when imprisonment began replacing other penalties and educational measures. Numerousbailiff residences were converted into prisons, including those of Saint-Jean (after serving as ahospice) and Thorberg in canton Bern. Prison architecture emerged as a distinctarchitectural genre as sentence execution became increasingly modulated with a view toward social reintegration.^[9]

TheEnlightenment postulates regardingjustice andpunishment led to the development of new construction programs that prevailed in the nineteenth century. Large carceral and penitentiary buildings constructed on foreign models were characterized by individualcells, work rooms, and courtyards for walks. The cohabitation of several hundred prisoners necessitated the introduction of measures againstescape andmutiny. To better supervise prisoners, buildings were constructed withradial wings equipped with narrow walkways leading to cells, easily supervised from the central hub (panoptic system). Numerous cantonal penitentiaries adopted the radial type:

• Geneva (two-wing building at right angles, constructed bySamuel Vaucher in 1822–1825, demolished in 1862),Lausanne (two-wing building on one axis, constructed byAdrien Pichard in 1819–1826, demolished in 1935)
• St. Gallen (three-wing building, constructed byFelix Wilhelm Kubly in 1836–1839, expanded in 1885 with two panoptic wings, demolished in 1958)
• Lucerne (three-wing building, constructed byGustav Mossdorf in 1861–1862)
• Lenzburg (five-wing building, constructed byRobert Moser [de] in 1864–1866)
• Basel (three-wing building, constructed by Robert Moser in 1860–1864)
• Neuchâtel (three-wing building constructed in 1867–1870 by Samuel Vaucher, demolished in 1956 and 1990)
• Regensdorf (four-wing building, constructed byHermann Fietz the elder in 1899–1901, demolished in 1995–1997).^[9]

Achapel was often positioned above the central hub;workshops were located below or behind the cell rows. The Bern penitentiary had the form of a classic square (constructed in 1826–1836 byJohann Daniel Osterrieth, demolished in 1898), designed for 400 detainees, only a portion of whom were housed in individual cells. Most cantonal penitentiaries were built between 1820 and 1870 on the periphery ofcantonal capitals. Large surrounding walls and barred windows, small and placed high, often oblong, of cellular wings revealed their function. Many have been demolished under pressure fromurban growth or replaced by constructions intended for other types of sentence and measure execution.

District prisons annexed toprefectures often met a similar fate: while theBienne prison has been preserved (constructed in 1886 byFranz Stempowski, became a regional prison), that ofLugano (constructed byAntonio De Filippis andGiuseppe Trezzini behind the court building, opened in 1873) was demolished.^[9]

By the nineteenth century, penitentiaries linked to agricultural exploitation existed, such asThorberg (1850),Saint-Jean (1883),Witzwil (1895),Hindelbank (1896, in thecastle until 1961, then in new buildings), andBellechasse (1898).Oberschöngrün (Biberist, 1924),Bochuz (1930, annex to thePlaine de l'Orbe colony founded in 1899), andWauwilermoos (1949) were constructed in the twentieth century. Some of these buildings, including Bellechasse (reconstructed in 1915–1919 bySamuel Blaser), resembled barracks, but most werepavilion colonies.Witzwil, composed of five farms, was early considered an example of a semi-open establishment (individual cell block constructed in 1895, new buildings erected in 1980–1985).^[9]

Theintercantonal concordats signed in 1956-1963 facilitated the establishment of a typology of carceral constructions according to sentence execution. The intercantonal penitentiary establishment ofBostadel (Menzingen, constructed in 1974–1977, according to a project by theBasel-City cantonal building office) consists of two small independent seven-story blocks; the median level is a sort of terrace surmounted by cells designed for 108 detainees.Pöschwies (Regensdorf, constructed in 1986–1988, expanded in 1997–1998) includes, besides a high-security quarter, sections reserved fordrug addicts, ordinary detention, and semi-freedom regime.^[9]

Some twentieth century constructions are distinguished by their architectural value. Notable examples include:

• Saxerriet (Sennwald, three pavilions, constructed in 1962–1964 byWerner Gantenbein; annex addition and renovation in 1998–2002 by architectsAschwanden Schürer)
• Etablissement d'exécution des peines de Bellevue (Gorgier, constructed in 1974–1976 byClaude Rollier andPhilippe Langel, contiguous staggered pavilions)
• La Tuillière (Lonay, constructed in 1989–1992 byFonso Boschetti andIvan Kolecek, pavilions aligned along a corridor).^[9]
