Thurgau: how this area actually works
Frauenfeld is the capital, inland from the lake. Kreuzlingen is the border town people actually see. They are not the same gate. Courts and the cantonal authority will not hand a stranger a name. German is the language on both shores and not the same law. kkjpd.ch will not search. A lakeside hotel in Romanshorn is a holiday unless the directions put the establishment there.
If the papers name a Thurgau unit, use its town. If they name St. Gallen, Zürich or Schaffhausen, switch canton. If they name a German facility, switch country. Women’s placement may be outside Thurgau. Do not invent one lake prison. Remand and sentence can differ. “Bodensee jail” is not a phrase the driver can resolve. Say Thurgau, not “Lake Constance prison,” to the driver. The lake has too many countries on it for that phrase to mean one gate.
Border life makes families casual. The gate is not. Probation in Frauenfeld is not a cell in Konstanz and not a cell in St. Gallen. If the person has been moved, leave the lake. Recheck. Summer ferries and winter fog both eat a same-day plan that was already aimed at the wrong town. Frauenfeld is inland. Kreuzlingen is the border town opposite Konstanz. Romanshorn is the lake. Pick the one in the directions. A German hotel in Konstanz is not a Swiss visiting base, and German police will not confirm a Thurgau placement.
Finding someone held in Thurgau
Confirm through the Swiss lawyer or the holding canton. Police will not read a list. Bring the date of birth and case number. Embassies need the country. A German authority does not hold the Swiss file. A news item from Kreuzlingen goes stale.
Write Frauenfeld, Kreuzlingen, or the real establishment. Foreign visitors should ask before they land at Zurich and rent a car for the lake. If the person is in St. Gallen, use that page. If the person is at Pöschwies, use Zürich. The lake is the wrong compass. If the establishment is in St. Gallen, Zürich or Schaffhausen, leave the lake. The Bodensee is a shore, not a concordat door.
Visits and family practicalities
Book with the Swiss holder if the custody is Swiss. No hours are printed here. German visiting rules from Konstanz do not apply. Check the live cantonal page.
Bring a passport. Children need permission and consent. Ask for an interpreter. Read the property rules. A ferry-day bag is the wrong bag. Summer ferries and winter fog are reasons to add time, not reasons the gate will wait. Book the Swiss visit first, then any crossing.
Getting around Thurgau
Frauenfeld is on the rail from Zürich toward the east. Kreuzlingen is the border branch. Zurich Airport is the usual flight. Use official directions. A pin on the lake, the German station in Konstanz, or Frauenfeld’s castle is not the entrance.
Add identification time and a border margin. Stay in the holding town. If you are in Germany, you have not started the Swiss visit. If the person is in another Swiss canton, leave the shore. Zurich trains make Frauenfeld feel close. Close is not the same as the right canton. Recheck before you rent a car for a shoreline you do not need.
