Birrwil

Isolated finds of artifacts indicate settlement during the Neolithic, Roman and Alamanni eras. The beginnings of the modern town go back to an Alamanni named Bero , who founded the village Beriwilare in the area. Birrwil is first mentioned in 1185 as Beriuuillare.
Between 1185 and 1331 there was a noble von Birrwil family. No traces remain of their family castle. The village was part of the lands of the Counts of Lenzburg, the Kyburgs and the finally the Habsburgs. The power of Zwing und Bann over the village, was held by the Lords of Hohenklingen through the von Birrwil family. In 1326 those rights were acquired by the Lords of Liebegg who held them until the 1798. Following the Bernese conquest of the Aargau in 1415 became part of Bern until the end of the Old Swiss Confederacy in 1798. The village became part of the Canton of Aargau following the 1803 Act of Mediation. The former manor houses were only fully incorporated in the 19th and 20th century into Birrwil .
