Kloster Muri
Prehistoric items have been found scattered on the banks of the former moraine, as well as Roman era objects. The modern municipality of Bünzen is first mentioned in 1259 as "Bunzina". In 1321 Muri Abbey acquired a "Meierhof" farm and church rights in Bünzen from Markwart of Rüssegg. After the conquest of the Aargau in 1415, the Swiss Confederation placed the village in the Hermetschwil district. The rights to low justice were held by the administrator of the "Meierhof".
