The center of Switzerland is on the Älggi-Alp in the canton of Obwalden . It was determined as the geographical center point in 1988 on the occasion of the 150th anniversary of the Federal Office for Topography.
The geographical center is actually the center of gravity . The calculation was carried out as a moment calculation with regard to the x and y axes for a closed polygon . This geometric center of gravity is the point at which a needle would have to be placed in order to balance Switzerland evenly . Imagine a Swiss map on homogeneous cardboard that is cut off along the national borders . In order to balance this piece of cardboard with a needle, cardboard Switzerland must be supported precisely at the centroid. This is on the Älggi-Alp at the coordinates
660 158 / 183640 ( 46 ° 48 '4 " N , 8 ° 13' 36" O ) . As this point is difficult to access above the cliff of Chli-Älggi, a publicly accessible stone was placed 500 m further southeast. This symbolizes the center and has the coordinates 660 557 / 183 337 ( 46 ° 47 '54 " N , 8 ° 13' 55" O ) .

Every year from 2003 to 2015, the Swiss of the Year was honored at this point and the name was engraved on the existing plaque .
Most distant point
In the Silbermoos near Uetendorf lies the Swiss center of the circle or the point of Switzerland furthest from the border. This is the point at which you are furthest away from any national border in Switzerland. According to calculations that have been carried out June 2019 at Swisstopo, the Federal Office of Topography, this point is located in Swiss coordinates (LV03) at the coordinates 610 170 / 181300 ( 46 ° 46 '58 " N , 7 ° 34' 19" O ) and is 68,880 meters from the border. Older calculations of the point had given the coordinates 609778/181368.

There are various calculation methods that are derived from the GIS system. With one, a lot of points are calculated for the distance to the national border and the area is geographically limited. This procedure is repeated and refined several times in the newly calculated area, with much closer intervals, and the center point is thus determined incrementally. Another method is based on the national border and draws polygons with increasing distance to it. This is repeated until the point furthest from the border is found in the last remaining area.

Remarks
↑ The center (focus) of Appenzell Ausserrhoden has not been marked as it is located in the canton of Appenzell Innerrhoden . In the meadow above the road and wall between Haslen and Vordergass (opposite the yellow house) is the geographical center of the canton of Appenzell Ausserrhoden.

↑ Between Schlattberg and Tannenberg, east of Haslen
↑ 213 m east-southeast of the Crap Furo is the geometric center of the canton of Graubünden (767576/169562) [2]. If you spear the canton on a needle in such a way that it remains in suspension, the tip of the needle protrudes from the ground in Crap Furo
