Thunstetten
Thunstetten is a municipality in the Oberaargau administrative district in the canton of Bern in Switzerland. History Thunstetten is first mentioned in 1220 as Tunchsteten.

As the Commandery grew, Thunstetten also grew. It had its own seal starting in 1274 and in 1320 entered into a Burgrecht agreement with Wangen. It entered into Burgrecht agreements with Bern in 1329, 1466, 1494 and 1504. Following the Protestant Reformation in 1528, the Commandery was secularized and its lands became the property of Bern. The former Commandery lands passed to the Bernese bailiff in Aarwangen. In 1711-13 Hieronymus von Erlach built Thunstetten Castle. Then in 1713 and 1721 he combined
