# Bergdietikon

Bergdietikon is a municipality in the district of Baden in the canton of Aargau in Switzerland. It is located in the Limmat Valley (German: Limmattal).

## History

Bergdietikon was originally part of the municipality of Dietikon in the Swiss County of Baden and was part of the short lived Canton of Baden. Following the Act of Mediation in 1803, the Canton of Baden was dismantled and the municipality of Dietikon was split. The mountain settlements in the west became the Berggemeinde Dietikon (Mountain municipality of Dietikon) until 1840 when it was renamed Bergdietikon. While Dietikon went to the Canton of Zurich, Bergdietikon went to Aargau. The creation of a municipality without any historic roots together and with a scattered geography meant that it took quite a while for any municipal center to appear.
