About this picture

Seegräben is a municipality in the district of Hinwil in the canton of Zurich in Switzerland .

coat of arms


Divided, above a silver dugout canoe in blue, below from the division four times stiffened by gold and blue

The dugout canoe in the coat of arms is related to the pile dwellers. Jakob Messikommer (Robenhausen / Wetzikon) researched a pile dwelling settlement in the Robenhauser Ried, in the municipality of Seegräben, in 1858 and thus carried out essential basic work on pile dwelling research.

The Seegräben community includes the village parts Seegräben, Aathal , Ottenhausen ZH , Steinberg, Aretshalden, Wagenburg and Sack. It is located directly at the southwest end of the Pfäffikersee in a gently rolling landscape.

Along the lakeshore there are some large reed areas , which are part of the nationally protected local recreation area around the lake. 49.9% of the municipal area is used for agriculture, 15.5% is covered with forest, 5.3% is traffic area and 10.4% is settlement area, 10.4% is water.

The topography is shaped by the moraines of the Linth glacier, which extended over the area during the last ice age. The Aabach flows through a valley on whose steep flanks the typical Nagelfluh (Aathal gravel) shows. There are numerous smaller and larger grottos in it. The largest of these, the so-called French Cave, is about 15 meters long and up to 2 meters high.


On December 31, 2019, 1,426 people lived in the Seegräben community.


On December 31, 2019, 40.88 percent of the population belonged to the Evangelical Reformed Church and 18.37 percent to the Roman Catholic Church .


The mayor is Marco Pezzatti ( FDP ) (as of 2014). His predecessor was Marlis Schmalzl ( SVP ) from 2010 to 2014 . Pierre Derron ( FDP ) was mayor until 2010.

Legislative is the municipal assembly.

In the 19th century the textile industry in the Aathal provided an economic boom. At that time the community changed from a farming village to an important industrial location. Agriculture lost its importance compared to industrial production. Today, the community is valued above all as a residential community that has good transport links to the rail network and the cantonal road network to Zurich. The S-Bahn Zurich serves the Aathal station with the S 14 Affoltern a. A. - Altstetten - Zurich HB - Oerlikon - Wallisellen - Hinwil . Starting in 2020, a 2-year pilot test of the 846 bus will run every half hour between Uster, train station and Seegräben, parish hall from May to October on the weekends.

Postbus line 909 used to run very irregularly from the parish hall to the SBB train station.

However, with the closure of the post office and the manned train station, the community has lost some of its infrastructure.

The Sack part of the village also houses the Villa RA school home.

The Aathal dinosaur museum in the village of the same name is very well known , as is the Römerbrünneli (city of Uster). The community also houses a section of the Zürcher Oberland industrial path. The village of Seegräben is of supraregional importance.

In the village part of Sack there are remains of an earlier protective wall, the so-called Heidenburg, which is acutely threatened by the planned motorway construction. In addition, finds were made in Ottenhausen, which indicate the existence of a Roman manor and a Roman road, which were presumably connected with the Irgenhausen Roman fort .

In the center of the village, right next to the church, is the Jucker family's farm, where the largest pumpkin exhibition in Switzerland takes place from late August to early November. The Winter Magic Christmas Market takes place in mid-November along Dorfstrasse.

The industrial plants in Aathal are listed and, thanks to their good condition, are important witnesses to the economic heyday of the Zurich Oberland in the 19th and 20th centuries.

The Pfäffikersee, on which Seegräben is located, is a popular excursion destination and recreation area thanks to its nationally protected reed areas.


Organ cycles and other concerts take place in the Seegräben church (see the website of the Seegräben community).
