The viral claim that an Italian town locks the year’s worst politician in a cage and dunks them in a freezing river mixes truth and fiction. The Tonca is a genuine ritual in Trento’s Feste Vigiliane involving a satirical mock trial and a symbolic immersion in the Adige, but the person who goes into the cage is a performer (historically Giorgio Vianini; in 2025 his daughter Tania). The event is theatrical, not punitive, and descriptions of the river as "freezing" in June are exaggerations.
Fact Check: Trento’s ‘Tonca’ Is A Satirical Dunking — Not A Real Punishment Of Politicians

In recent months social posts have claimed that an Italian town annually locks the politician responsible for the year’s worst decision in a cage and plunges them into a freezing river. That story mixes fact and fiction: it is based on a real ritual in Trento, but key details are theatrical rather than literal.
What The Tradition Is
La Tonca is a long-running feature of Trento’s Feste Vigiliane, the city festival that honors its patron saint, San Vigilio. The modern ceremony pairs a satirical mock trial — the Tribunale di Penitenza — with a symbolic immersion in the Adige River. The sequence is presented as public theatre, mixing irony, comedy and popular participation.
What The Viral Claims Get Right
There really is a ritual in which a person in a cage is lowered into the Adige after a mock verdict. The Tonca draws on historical punishments (14th–17th centuries) and is staged each June as part of the Feste Vigiliane program.
What The Viral Claims Get Wrong
- The event is not a literal punishment of a real politician: it is a satirical performance.
- The individual placed in the cage and immersed in the river is a performer or stand-in (tramite controfigura), not the actual public figure named by the tribunal.
- There is no evidence the Adige is "freezing" during the June festival; references to icy water are dramatic exaggeration.
Who Goes Into The Cage?
For decades the role of the Tonca’s stand-in was Giorgio Vianini, a local volunteer who first participated in 1985 and became the ritual’s familiar face. After Vianini’s death in November 2024, his daughter Tania took over the role in 2025. Local coverage and festival materials explicitly describe the immersion as carried out by a performer rather than by the figuratively "condemned."
Who Are The Targets?
The mock tribunal’s "condemned" can be politicians, private citizens, symbolic objects, animals or even abstract phenomena. Examples: in 2023 the target was a symbolic "bear" scapegoat; in 2019 multiple local politicians were named; in 2025 the list included provincial figures and non-voters. The Tonca sometimes singles out more than one target in a single year.
How The Ceremony Has Varied
The format has adapted over time. During the COVID-19 pandemic the tribunal took place online (2020), and the post-pandemic edition once used a bucket-based dunking rather than a river immersion. Recordings from multiple years (2012, 2014–2016, 2019, 2023, 2025) are publicly available and show the event as theatrical.
"The Tonca is a public performance blending theater, satire and popular participation," reads the festival’s description. Local reporting frames the event as symbolic, not punitive.
Bottom line: the Tonca exists and features a caged immersion, but it is ceremonial theatre. Social posts that portray it as an annual practice of imprisoning and dunking the year’s worst politician in a freezing river conflate satire with reality and exaggerate environmental details.
