context_page_description: The canton of St. Gallen, also canton of St Gall, is a canton of Switzerland. The capital is St. Gallen.
  Located in northeastern Switzerland, the canton has an area of 2,026 km² and a resident population close to half a million as of 2015. It was formed in 1803 as a conflation of the city of St. Gallen, the territories of the Abbey of St. Gall and various former subject territories of the Old Swiss Confederacy.
context_section_description: The canton is located in the north east of Switzerland. It is bounded to the north by Lake Constance (Bodensee). To the east lies the Rhine valley. Over the Rhine are Austria (state of Vorarlberg) and Liechtenstein. To the south, the canton of St. Gallen is bounded by the cantons of Graubünden, Glarus and Schwyz. To the west lie the cantons of Zürich and Thurgau.
  The two half cantons Appenzell Innerrhoden and Appenzell Ausserrhoden are completely surrounded by lands of the canton of St. Gallen.
  The main rivers of the canton are the Rhine, Thur, Linth and Seez. The topography changes from the plains, near river Rhine and Lake Constance, towards the mountainous areas of the Alps in the south (Appenzell Alps and Glarus Alps). About one third (619.7 square kilometers (239.3 sq mi)) of the canton is wooded, while nearly half is 9,790.6 km² (3,780.2 sq mi) is used for farming. 278.6 km² (107.6 sq mi) of the farm land is alpine pastures. Of the rest of the canton, 259.1 km² (100.0 sq mi) is considered unproductive while 176 km² (68 sq mi) is filled with housing or roads.
  The altitude above the sea-level varies from 398 m (1,306 ft) (the lake of Constance) to 3,251 m (10,666 ft) (the Ringelspitz). The canton includes portions of the lake of Constance (54 km² (21 sq mi)), of the Walensee (rather over 18 km² (6.9 sq mi)), and of the lake of Zürich (10 km² (3.9 sq mi)), and several small lakes wholly within its limits.
  The mountains of the canton include part of a thrust fault that was declared a geologic UNESCO world heritage site, under the name Swiss Tectonic Arena Sardona, in 2008.
