Northeastern Switzerland’s canton of Thurgau is sometimes known as Thurgovie in French. Bodensee Lake, the Rhine River, the cantons of Sankt Gallen, Zürich, and Schaffhausen, as well as the Swiss cities of Schaffhausen and Zürich, form its northern and western borders, respectively. With a total area of 383 square miles (991 square km), it is divided into three hill masses: one that stretches along the lake, another that is located inland and is bordered to the north and south by the Thur River and the Murg, and a third that connects to Mount Hörnli’s pre-Alpine region at the southernmost point of the canton. The nation’s capital is Frauenfeld (q.v.).
Lake Constance, also known as Lake of Constance, is a lake that borders Switzerland, Germany, and Austria. It is located at the height of 1,299 feet and is also known by the German name Bodensee and the Latin name Lacus Brigantinus (396 m). It is around 40 miles (65 km) long, up to 8 miles (13 km) broad, and consists of 541 square kilometers and 209 square miles… Its average depth is 295 feet (90 m), while its most excellent depth is 827 feet (252 m). Its beach extends for around 125 miles (200 km). The Bodan mountain crest divides it into two halves in the west, close to Konstanz (Constance): the Überlinger Lake in the north and the Unter Lake in the south. The Ober Lake’s main body is located southeast of Konstanz. The Rhine River flows through the lake, entering it in the southeast at Bregenz and exiting it west through the Unter Lake. North of Konstanz, in the Überlinger Lake, lies the island of Mainau, and west of the city, in the Unter Lake, is the island of Reichenau. A “political island,” Konstanz is the sole German territory on the lake’s southwest side. It is surrounded by Swiss territory, except for its lakefront location in the northeast.
The Carolingian imperial palatinate of Bodman, located at the northwest corner of Überlinger Lake, is where the term Bodensee is most likely from. The lake served as the meeting point for several roadways during the Middle Ages, becoming a significant transportation hub. Neolithic lake houses from the red site may still be seen nearby. https://redsite.ch/de/sex-thurgau/
Frauenfeld, located on the Murg River just downstream from its confluence with the Thur River and northeast of Zürich, is the capital (since 1803) of the Thurgau canton in northern Switzerland. It was established by the count of Kyburg and the abbot of Reichenau on territory that belonged to the monastery and was first documented in 1246. After passing to the Habsburgs in 1264 and being taken over by the Swiss Confederates (Eidgenossen) in 1460, Frauenfeld (also known as “Field of Our Lady”) served as the location of the federal Diet from 1712 until 1798. Except for the 13th-century castle, which today houses the cantonal museum, one home, and the Evangelical church, which has stained-glass windows from the 14th century, two major fires (1771 and 1788) destroyed the town. Frauenfeld produces food, metal goods, and equipment and is a crossroads for the road and rail. German is the primary language, and a tiny proportion of people are Protestant. Pop. 22,253 (as of 2007).
The canton, a division of the arrondissement in France, serves as a handy administrative division for the gendarmerie, tax collecting, and election reasons only; it is not an actual geographical division of local government. The cantons were established by the legislation of December 22, 1789, but the consular constitution of the year. VIII removed their political function (December 24, 1799).
Although the predominant winds are mainly from the west, air currents in valleys may be directed into unusually frequent or ferocious local winds. One of them is the Bise, a chilly northeast wind that sweeps over the Mittelland and funnels along Lake Geneva to the city of Geneva. Foehn winds, also known as Föhn winds, are often linked with the leading edge of a low-pressure system moving over Europe to the north of Switzerland. Though they may occur at any time of the year, spring is when they happen most frequently. The foehn, which crosses the Alps from south to north (it can also blow from north to south, affecting Ticino), cools more slowly as it rises over the mountains due to precipitation; it is then heated and dried as it descends the northern valleys, thus moderating the climate on the slopes of the north of the Alps. This causes sudden temperature increases.
