About this picture

Boniswil ( Swiss German [ ˌbɔniʃˈʋiːʊ ]) is a municipality in the Swiss canton of Aargau . It belongs to the Lenzburg district and is around eight kilometers south of the district capital in the Seetal , at the northwest end of Lake Hallwil . In 1898 Alliswil was incorporated.


The village is located about one kilometer west of Lake Hallwil on the edge of the Seetal on an elevated terrace. Extensive swamp areas with reed belts , which are under nature protection , extend along the lake shore . The Aabach forms the eastern boundary of the municipality. To the west of the village center, the terrain rises steeply up to the Leutwil plateau . Alliswil is located one kilometer south of the village .

The area of ​​the municipality is 241 hectares , of which 21 hectares are forested and 58 hectares are built over. The highest point is at 578  m above sea level. M. on the southwestern boundary of the municipality, the deepest at 448  m above sea level. M. am Aabach. Neighboring communities are Hallwil in the north, Seengen in the northeast, Meisterschwanden in the southeast, Birrwil in the south, Leutwil in the west and Dürrenäsch in the northwest.


Neolithic pile dwelling settlements are suspected on the Risi peninsula . The first documentary mention of Bonoltswile took place in 1220 in the land register of Einsiedeln Abbey , which maintained a farm for the administration of its extensive goods in the area. The place name comes from the Old High German Banwalteswilari and means "Hofsiedlung des Banwalt". In the Middle Ages the village was under the rule of the Counts of Lenzburg , from 1173 on that of the Counts of Kyburg . After these were extinct, the Habsburgs took over sovereignty and blood jurisdiction in 1273 . Since the 13th century, the lords of Trostburg had held the lower jurisdiction . This right fell to the Lords of Reinach through inheritance in the mid-14th century .

In 1415 the confederates conquered Aargau. Boniswil now belonged to the subject area of ​​the city of Bern , the so-called Bernese Aargau . The village was part of the Trostburg judicial district in the Lenzburg district . This district was owned by the Hallwyler from 1486 to 1616 and then also came to Bern. In 1528 the Bernese introduced the Reformation . In March 1798 the French took Switzerland, ousted the «Gracious Lords» of Bern and proclaimed the Helvetic Republic . Boniswil has been part of the canton of Aargau since then.

At the end of the 18th century, the village developed into an important trading center for the cotton industry. At that time, several hundred spinners and weavers were working from home making colored cloths. In the middle of the 19th century, straw weaving emerged and replaced cloth weaving. On October 15, 1883, the community was connected to the railway network when the Seetalbahn opened the Lenzburg– Beinwil am See section . In the same year the first cigar factory was opened, soon followed by a candy factory and three box factories . The neighboring village of Alliswil was incorporated in 1898 by order of the cantonal government. The population remained largely constant until the early 1960s; since then it has doubled due to increased construction activity. Boniswil developed into a residential community.

The current variant was introduced in 1953.
