About this picture

Dietikon (in local dialect : [ ˈd̥iə̯tikχə / ˈtiə̯tikχə ]) is a political municipality and capital of the district of the same name in the canton of Zurich in Switzerland . Dietikon had a population of 27,000 at the end of 2016. With the strong economic development of the Limmat Valley since the end of the Second World War , the city became a city in the agglomeration of Zurich . Due to the brisk construction activity, the two formerly separate villages of Dietikon Unterdorf and Dietikon Oberdorf grew together. Inhabitants of Dietikon are called dieticians. Dietikon should not be confused with the almost homophonic political community Dietlikon in the Bülach district east of the city of Zurich.


The industrial city of Dietikon is located west of the city of Zurich at 388  m above sea level. M. at the confluence of the Reppisch and Limmat and on the railway line from Zurich to Baden . The large Limmattal marshalling yard is also located here and in the neighboring town of Spreitenbach . Approx. 25% (2.3 km²) of the area is forest. The largest and best known are Honeret, Guggenbüel and Röhrenmoos.


The Honeret lies on a lateral moraine of the Linth glacier . There are therefore over 200 striking stones and boulders up to 25 m² in size (boulders). The Honeret and the Guggenbüehl forest are only separated from each other by a main road. In the forest there are some springs from which the Tobelbach and Stoffelbach streams emerge and then flow into the Reppisch. The forest hut Lorenzhütte is located in the forest.


The Guggenbüehl is entirely in Dietikon. The Giigelibode pond is in the forest . It has neither inflows nor outflows. There is a Vita Parcours in the forest .

Grien Island:

The Grien Island lies between the Limmat in the east and a canal of the Dietikon power plant (electricity works of the Canton of Zurich) in the west.

Important bodies of water that flow through Dietikon are the Limmat and its tributary Reppisch as well as the approximately 6 kilometers long Schäflibach and Teischlibach . The Teischlibach rises in the Röhrenmoos forest above Dietikon and also flows into the Limmat. The marble pond is located in the Grunschen , a playground and barbecue area. The Marble Pond is an artificial pond that was created to supply the fire brigade with extinguishing water. For this purpose, a diversion channel was built at the Grunschen . The pond was later used by a marble factory. This is what gave it its name.


The finds that were made in the Schächteli allow the conclusion that the area was already populated in the Neolithic Age (5500-2400 BC). Settlement during the Bronze Age can be proven with grave finds on the Honeret and in the former village center. Graves from the Iron Age have also been found, which can be ascribed to the Hallstatt and Latène periods .

From AD 20 to around AD 320 there was a large Roman estate in the area of ​​today's city center. It covered at least an area of ​​13,000 square meters and was at least 212 × 600 meters in size. The manor was surrounded by a wall, the height of which is estimated to be one meter. In the south-east of the area there was a villa area, the extent of which towards the Limmat is unclear. It is also assumed that there was a landing stage for ships on the Limmat. The manor was largely destroyed by fire in the middle of the 3rd century. The manor was on the Roman road from Lake Zurich via Baden to Vindonissa .

The settlement in the early Middle Ages is proven by graves from the 7th century. Based on the pit houses , which were located in the area of ​​the Catholic Church, it must be assumed that there has been continuous settlement since the 10th century. In the chronicle of 1135 written by Ortlieb, Dietikon is mentioned for the first time in the description of the Bempflingen Treaty . It says there that Kuno von Wülflingen bequeathed to Dietinchovin "a quarter of the village, church and Limmatfischenz as well as Salland in a total of 12 Huben" to the Zwiefalten monastery, which he founded . The place name consists of the Old High German personal name Dioto, extended by the suffix -ing- and the appended basic word hof in the plural dative ( * Diotinc-hovun > Dietikon ) and means something like 'at the courtyards of the Dioto clan'.

The monastery sold its property in Dietikon as early as 1096 to the wife of Count Otto von Habsburg , the dynasty that briefly owned the entire village (Unter- and Oberdorf) and all of their property in Dietikon (Unterdorf) and Schlieren sold to Wettingen Monastery in 1259 for 540 marks. The Habsburgs retained the county rights ( high court ), customs, patronage and the bailiwick of the church. As employers of the Habsburgs, the knights of Schönenwerd moved into Schönenwerd Castle on the Limmat. Even after Dietikon was sold, they exercised the bailiwick rights over Dietikon-Oberdorf, which was then considered a separate bailiwick. Here on the Reppisch the knights owned a sizable property. The Wettingen monastery gradually succeeded in buying the possessions in the upper village from the impoverished knights. The bailiwick rights of both Dietikons did not come to the monastery until 1367. Within a century, the monastery succeeded in acquiring an almost closed area with all rights around Dietikon, so that one can speak of a Dietikon rule. The monastery then shaped the village. As the legal successor to the secularized monastery, the canton of Aargau sold the Dietikon church treasure to the Zurich stand . The contract for this was signed on March 3rd and 17th. Only after the Reformation did Zurich slowly make itself felt.

The county rights, and thus the high court, were initially with the Habsburgs until the Confederates conquered Aargau in 1415 . Until 1798 Dietikon belonged to the Landvogtei Baden and was therefore part of the County of Baden and the common rulership of eight places (after 1712 only Zurich, Bern, Glarus). After the French invaded, the canton of Baden of the Helvetic Republic was founded on April 11, 1798 , to which Dietikon also belonged. On September 25, 1799, the place was the scene of the Limmat crossing of the French . When the Helvetic Republic was dissolved on March 10, 1803, Dietikon became part of the Canton of Zurich. Between 1815 and 1832 the community belonged to the Zurich Oberamt and from 1832 to the Zurich district . On July 1, 1989, the Dietikon district was split off from the Zurich district and Dietikon was named the district capital.

In 1939 the center of Dietikon was expanded with bunkers and a concrete ring wall into an important base, the so-called Dietikon Fortress , the position of the Limmat . In 1940 it was inspected several times by General Henri Guisan . The central school building served as a mobilization space. It was surrounded by defensive walls and bunkers. Soldiers were quartered, changing of the guard and main reading took place in the playground. Parts of the Dietiker fortifications have been preserved to this day - including two longer pieces of the former fortress wall in the middle of the city.

The Roman Catholic Church of St. Agatha , which was built between 1925 and 1927 according to plans by Adolf Gaudy , is the most visible building in today's city center. Behind her is the Catholic rectory (Bahnhofplatz 3A), which was built in 1833. The reformed church was built away from the village center. It is located on the Kirchhalde and was built between 1924 and 1925 according to plans by Emil Schäfer. Before that there was a parity church in Dietikon , the Church of St. Ulrich and St. Agatha, which was then demolished. The Bruno Weber Park at the Dietikon town hall is also very popular and the 80 meter high Limmat Tower has established itself as a new landmark in Dietikon in the Limmatfeld. It was completed in 2015.

The road from Zurich to Baden has passed through the district of Dietikon-Unterdorf since the Middle Ages. As far as it can be reconstructed, it follows the old Roman road and, like this one, crosses the Reppisch. The main road over the Mutschellen, which leads from Zurich to Bremgarten, was built between 1840 and 1841. The municipality has owned the Dietikon train station since 1847 , although the first station building from 1847 has been preserved. With the opening of the Bremgarten-Dietikon-Bahn, it became a transfer station. The Glanzenberg train station is also part of the city of Dietikon, where the Zurich S-Bahn also stops. There are also four further train stops operated by BDWM Transport AG: Schöneggstrasse, Bergfrieden, Stoffelbach and Repischhof. With the opening of the A1 motorway in 1970, the full connection to Dietikon was also created. The regional bus transport is carried out by the Limmat Bus company.

Together with the second generation of the Zurich S-Bahn, a new station is to be built in the Silbern industrial area. The largest Tesla location in Switzerland to date was opened there in May 2019, with 24 Tesla Superchargers and a lounge , etc. a. with drinks machine , catering machine and game console , opened.
