Teufen is a municipality in the canton of Appenzell Ausserrhoden in Switzerland.
Teufen was first mentioned in 1272. By 1300 the place consisted of only five farms. In 1525 the assembly ruled that each parish could decide whether or not to remain Catholic. This led to the division of Appenzell in 1597.
In 1841 Teufen offered their new school building as a present to attract the government of the canton. The assembly refused the present.
Weaving was important for Teufen and the Swiss economy. Around 1820 a new loom was invented in Teufen, allowing embroidery in one go. This led to a large boom in the embroidery industry, particularly between 1880 and 1890.
Switzerland has the best maintained hiking trails. It is very easy to do a daily hike around the neighborhood and farms.
