Thun | Switzerland

Thun functions as the administrative and military capital of the Bernese Oberland and the northern gateway to the Alps. Situated where the Aare River flows out of Lake Thun (Thunersee), it is a major center for the Swiss Armed Forces and specialized precision engineering.

Historical Timeline

Thun originated as a prehistoric lakeside settlement before becoming a Roman administrative post. The primary era of governance was established in the 12th century by the Dukes of Zähringen, who constructed the city's landmark castle. The primary event shaping its modern structure was its 1384 acquisition by Bern, followed by the 1819 establishment of the Federal Military School, which made Thun the most important military garrison in Switzerland.

Demographics & Population

The population is approximately 44,000, making it the eleventh-largest city in Switzerland. The demographic is characterized by a high concentration of military personnel, engineers, and service professionals. German is the official language, with Bernese German as the spoken vernacular. The median age is 43.1 years.

Urban Layout & Key Districts
