Davos

Blading: Foursquare of blue and gold, covered with a cross in mixed colours.

Surviving coat of arms of the Zehngerichtebund. Probably the original coat of arms of the Zehngerichtebund was a yellow cross on a blue background. This colour distribution and the cross shape were clearly visible and easy to describe.

Davos landscape

The territory of the Davos landscape comprises most of the Landwasser valley and extends a good two kilometres beyond the watershed into the Prättigau at Davos Wolfgang (1631 m). The axis of the valley, marked by the river, main road and railway line, runs from northeast to southwest. From the Davosersee, it initially slopes very gently, only just under 60 metres over a length of eight kilometres. In this section, the two side valleys of Flüela and Dischma flow into the valley from the left, providing access to the Flüela Pass and Scaletta Pass, respectively, which lead into the Engadine. From the confluence of the third side valley, the Sertigtal, which is about 10 km long like the aforementioned ones, the valley floor becomes narrower and drops by almost 300 metres over the remaining nine kilometres to the former municipal boundary at the Felsenge Brombänz. The deeply cut lower section of the valley is called Zügenschlucht. Beyond the Zügenschlucht is the fraction of Wiesen, which has also belonged to Davos since 1 January 2009.

The right (north-western) flank has only a few short side valleys. Here the municipal boundary - at the same time watershed against the Plessur region - runs over the summits of Amselflue (2771 m), Tiejer Flue (2781 m), Mederger Flue (2674 m) and Chüpfenflue (2658 m) to the historically important Strelapass. Beyond the saddle it continues over the Schiahorn (2709 m) to the Weissflue (2834 m). To the north, the municipal boundary runs along the Casanna and Gotschnagrat. The left side of the valley is dissected by the three side valleys into protruding ridges. Viewed from the valley, the mountains Seehorn (2238 m), Büelenhorn (2512 m), Jakobshorn (2590 m) and Rinerhorn (2528 m) dominate the scene. The highest peaks, however, are found along the watershed towards the Engadine and the upper Albula valley: Flüela Wisshorn (3085 m), Flüela Schwarzhorn (3147 m, highest point in the municipality), Piz Grialetsch (3131 m), Chüealphorn (3078 m) and Hoch Ducan (3063 m).

Villages of Davos

The six districts - autonomous fractional municipalities until the end of 2018 - are in the direction of flow of the river Landwasser:

• Davos Dorf, including the Flüela valley, the settlement of Wolfgang with the road crossing Passhöhe Wolfgang and the hamlet of Laret beyond the pass,
• Davos Platz, including the Dischma Valley,
• Davos Frauenkirch, including the Sertig valley,
• Davos Glaris
• Davos Monstein (since 2019 the only local authority under public law in the municipality)
• Davos Meadows

The Frauenkirch, Glaris and Monstein fractions together form the undercut, while the Platz and Dorf fractions form the overcut.

The two largest fractions, Dorf and Platz, lie in the almost flat upper section of the valley and have merged into an approximately four-kilometre-long band of settlements as a result of building activity in the 20th century. A large number of individual farms and alpine settlements are scattered throughout the municipality.

With 254.54 km², Davos was the second largest municipality in Switzerland in terms of area until the beginning of 2009. In 1997, 37.1 % of the area was used for agriculture as meadows and pastures, the forest took up 19.7 % and settlements 2.2 %. Unproductive land accounted for 41.0 %.

With the incorporation of Wiesen, Davos became Switzerland's largest municipality by area at the beginning of 2009, just ahead of Bagnes (282 km²), but lost this leading position again at the beginning of 2011 to the newly created municipality of Glarus Süd.

Neighbouring communities are Arosa, Bergün Filisur, Klosters-Serneus, S-chanf, Schmitten and Susch.
