Davos Switzerland Postcard. The current settlement of the Davos area started back in High Middle Ages with the immigration of Rhaeto-Romans. From about 1280, the barons of Vaz allowed German-speaking Walser colonists to settle down, and conceded them extensive self-administration rights, causing Davos to become the largest Walser settlement area in eastern Switzerland. Natives still speak a dialect that is atypical for Graubunden, showing similarities with German idioms of western parts of Switzerland, such as in Bernese Oberland and the Upper Valais. Davos became a famous ski resort, especially frequented by tourists from the United Kingdom and The Netherlands. After peaking in the 1970s and 1980s, the city settled down as a leading but less high-profile tourist attraction. Size 4 x 6 inches.
