These layers, like the ones of the Jura Mountains, were deposited in a relatively shallow sea, the Tethys Ocean . Above the Mesozoic layers, is the Molasse , consisting of conglomerate , sandstone , marl and shale . The uppermost layer consists of gravel and glacial sediments that have been transported by

819-462: Is given in the following table: Since January 2011, Thurgau has been divided into five districts which are named after their capitals. Before this date, there were eight districts - ( Steckborn District , Bischofszell District and Diessenhofen District formed their own districts with their surrounding municipalities). As of 2009 , there are 80 municipalities in the canton . The ten largest municipalities by population are: The canton of Thurgau

882-513: Is highly developed. The most important transversal, so to speak the backbone of the Swiss Plateau, is the A1 motorway that connects all the big cities going from Geneva over Lausanne, Bern, Zürich and Winterthur to St. Gallen. The A2, the Swiss north-south axis, crosses the plateau from Olten to Luzern. The railway network is very dense. All major cities are connected, and between Olten and Lausanne, there are two main lines: One passing over Bern and Fribourg,

Occasionally the regions of the higher Swiss Plateau, especially the hills of the canton of Fribourg , the Napf region, the Töss region, the (lower) Toggenburg , and parts of the Appenzell region are considered to form the Swiss Alpine foreland in a narrow sense. However, if a division into the three main regions Jura Mountains, Swiss Plateau and Alps

1197-543: The Canton of Thurgau , is one of the 26 cantons forming the Swiss Confederation . It is composed of five districts. Its capital is Frauenfeld . Thurgau is part of Eastern Switzerland . It is named after the river Thur , and the name Thurgovia was historically used for a larger area, including part of this river's basin upstream of the modern canton. The area of what is now Thurgau was acquired as subject territories by

1260-616: The First War of Villmergen (1656), during which Zurich briefly occupied the Thurgau. In 1798 the land became a canton for the first time as part of the Helvetic Republic . In 1803, as part of the Act of Mediation , the canton of Thurgau became a member of the Swiss confederation. The cantonal coat of arms was designed in 1803, based on the coat of arms of the Kyburg family, which ruled the Thurgau in

1323-464: The Lake Baldegg . Another reminder of the glaciation are glacial erratics which are found all over the Swiss Plateau. These rocks, sometimes of enormous size, are of alien stones, mostly granite and gneiss from the central crystalline Alps. Taken together, they were one of the clues that led to the substantiation of the glaciation theory in the 19th century since transport by water or by volcanism

1386-492: The Pfyn culture along Lake Constance . During Roman times the canton was part of the province Raetia until 450, when Alemanni settled on the lands. In the sixth century, Thurgovia became a Gau of Francia as part of Alamannia , passing to the Duchy of Swabia in the early 10th century. At this time, Thurgovia included not just what is now the canton of Thurgau, but also much of

1449-411: The Rhine advanced sometimes as well until the Jura. The glaciers formed the land by erosion, but also by base moraines (very fine stone meal) often several meters thick, and by the meltwater streams depositing gravel. Traces of the older Günz and Mindel glaciation are only left in a few places because most have been removed or transferred by the later glaciations. The greatest extension was reached by

1512-803: The Suhre , the Seetal , the Reuss and the Limmat ). The Rhine Glacier has mostly left traces that trend west: The eastern Swiss Plateau of the Thur Valley and Lake Constance. In certain places, there are characteristic drumlins of the base moraine, often clustered, especially in the highlands of Zürich, in the Hirzel region, in the Lake Constance region and between the Reuss Valley and

1575-495: The glaciers of the ice ages . Geologically the most important layer of the Swiss Plateau is the thick molasse sequence that accumulated at the border of the Alps due to the rapid erosion of the concurrently uplifted mountains. The thickness of the molasse increases from west to east (at the same distance from the Alps). The former alpine rivers built huge fans of sediment at the foot of

Major oppida were built after the Celts appeared in the 3rd century BC. Urban settlements with stone houses were built during the Roman Empire . The Swiss Plateau became a part of the Roman Empire in 15 BC when

1764-469: The Alps and the Jura can have the brightest sunshine. Typical for the high fog is the bise , a cold wind from the northeast. Since it is channelled by the Swiss Plateau narrowing in the southwest, it reaches its major strength in the Lake Geneva region where wind speeds of 60 km/h with top speeds of more than 100 km/h are usual in typical bise weather. The regions near the Alps of the central and eastern plateau sometimes have temperature rises due to

1827-500: The Alps. The central Swiss Plateau is characterised by a number of ranges and broad valleys, some of them with lakes, that run northwest. The last of them is the Albis range, which together with the Heitersberg range forms a bar from the Alps to the Jura that the major transportations bypass only in a few places, mostly in tunnels. The eastern Swiss Plateau is structured by the valleys of

1890-466: The Ice Age glaciers, there is plenty of gravel and clay. The gravel digging in the Ice Age gravel terraces all over the Swiss Plateau covers the demands of the construction industry. Numerous hydroelectric power plants in the rivers produce electricity. All four Swiss nuclear power plants are situated on the plateau. Because of the comparatively easy topography and the dense population, the transport network

1953-463: The Jura, clays and marl. During the Tertiary orogenic uplift , around 60 – 40 million years ago, the area of today's Swiss Plateau was a Karst plateau somewhat inclined to the south. Through processes of rising and lowering that were brought by the folding of the Alps, the area was twice flooded by a sea. The corresponding sediments are distinguished as sea molasse and freshwater molasse, even though

In 1524, in an incident that resonated across Switzerland, local peasants occupied the cloister of Ittingen in the Thurgau, driving out monks, destroying documents, and devastating the wine-cellar. Between 1526 and 1531, most of

The base level is crystalline basement which outcrops in the central crystalline Alps as well as in the Black Forest and the Vosges mountain range but forms a deep geosyncline in the Swiss Plateau and in the Jura (see also Jurassic ). Around 2500 – 3000 metres below the surface, but considerably deeper near the Alps, the drillings have hit the crystalline basement. It

In the following time, especially the western part of the plateau was again significantly risen, so that in this area, the sediments of the upper sweetwater molasse and the upper sea molasse have been largely eroded. A characteristic of the sea molasses is fossil snails, shells and shark teeth, whereas in
