Map - Spreitenbach

Spreitenbach (High Alemannic: Spräitebach) is a municipality in the district of Baden in the canton of Aargau in Switzerland, located in the Limmat Valley (German: Limmattal).

It lies southeast of the district center, directly on the border with the canton of Zurich. It is one of the smallest cities in Switzerland. In Switzerland, a city needs a population of 10,000 or more to be considered as a city.

The town lies between Baden and Zurich on the south side of the Limmat, located in the Limmat Valley. The settled area stretches along a plain between the Heitersberg and the waterfront. The old town center, through which the Spreitenbach stream flows, lies to the south and has preserved its original character well. North of that is the modern city, with wide apartment buildings, industrial areas, and shopping centers. To the far north, across the highway and railway, in a bend in the Limmat, is the expanded industrial zone Neuhard. The eastern part of the plain is dominated by the classification yard Zurich-Limmattal.

The Franzosenweiher ("French pond") lies in the forested area south of Spreitenbach, near the municipal border with Dietikon. The "Altes Bad" biotope is made up of a pool and a wetland with a great diversity of plants. The municipality has set aside this area and the neighboring forest as a protected natural zone. The name comes from the fact that Napoleon's troops camped at the pond, before crossing the Limmat at Kloster Fahr.

Around 2 km west of the town, at a height of 650 m, lies Heitersberg, a hamlet set on a high plateau in the Heitersbergs. Not far from there is the highest point in the municipality (672 m). The lowest point, 385 m, is the Limmat. Spreitenbach has an area,, of 8.6 km2. Of this area, 27.8% is used for agricultural purposes, while 35.3% is forested. Of the rest of the land, 35.5% is settled (buildings or roads) and the remainder (1.4%) is non-productive (rivers or lakes).
