# Berikon

Berikon is a municipality in the district of Bremgarten in the canton of Aargau in Switzerland.
The village lies on a hill above and to the east of the Reuss Valley, covering part of the Mutschellen Pass. This municipality is bounded by Rudolfstetten-Friedlisberg, Widen, Zufikon, and Oberwil-Lieli, all in canton Aargau, and shares a boundary with the canton of Zürich (district of Dietikon) to the east.

## History

Berikon was mentioned for the first time in 1153 as a court place "Berchheim". In 1184 it was mentioned as Berchein. Over time, the name of the place changed from Berchheim to Bergheim, then to Berchan, Berkein, and finally Berikon.
The originally separate settlements Unterberikon (Lower Berikon) and Oberberikon (Upper Berikon) fell under the territorial lordship of the city of Zürich in 1415, when the Eidgenossen (Confederacy) conquered Aargau. Later, in 1471, Unterberikon became part of Amt Rohrdorf in the county of Baden, while Oberberikon fell under the oversight of the Kelleramt (Freiamt Affoltern).
When in 1798 the French overran Switzerland and instituted the Helvetic Republic, both municipalities came to the short-lived canton of Baden. During the establishment of the canton of Aargau in 1803, the two municipalities were reunited and joined the district of Bremgarten.
On 1 May 1902, the Bremgarten-Dietikon-Bahn was opened, giving Berikon a railway connection to the rest of Switzerland. Still, until well into the 20th century, Berikon was a rural village, populated by just 900 inhabitants in 1950, before a sudden boom of construction activity occurred. Within thirty years the total population increased by over 150%. Today's population is roughly quadruple that of the 1960s. Berikon has grown together with the neighbouring municipalities and is today part of the agglomeration of Zürich.

The municipality is located in the Bremgarten district, and is located on the Mutschellenhöhe. It consists of the originally separate villages of Ober- and Unter-Berikon.

## Transportation

The Berikon-Widen station of the Bremgarten-Dietikon-Bahn stands right on the Mutschellen pass. This station is a stop of the S-Bahn Zürich on the line S17 serviced by the Bremgarten-Dietikon-Bahn. Buses of two Postauto lines, each with a terminus at Berikon-Widen station, connect the Mutschellen communities with Baden to the north and Zürich at the Wiedikon station to the east. The No. 350 Postauto line to Zürich Wiedikon also affords a good connection in Birmensdorf with the S9 and S15 train lines to Zürich, Affoltern am Albis, and Zug.
Before the A1 expressway was built, the Mutschellen pass was the main connection for auto traffic between Zürich and Bern. Now, the road to Bern (Bernstrasse or Hauptstrasse 1) is still an important carrier of road traffic, particularly commuters. With the completion of the A4 expressway (scheduled November 2009) much more traffic (at least 5% by 2015) is expected through Berikon for travellers heading for the interchange at Birmensdorf (approx. 3 km away). Berikon has begun roadwork with a view to reduce the flow of transit vehicles. The project implementing these remedial measures is planned to last some 2.5 years and should be completed in autumn of 2011.
