The landscape is not dissimilar to that of the Tafeljura, even though - geographically and geologically speaking - Gränichen lies in the Midland of Switzerland.

These are foothills of the Schornig (596 m (1,955 ft)), which marks the transition to the valley of the river Suhre.

Of the rest of the land, 13.1% is settled (buildings or roads) and the remainder (0.1%) is non-productive (rivers or lakes).

[4] However, archaeological discoveries dating from the Neolithic, as well as the remains of a Celtic castle, show that the area around Gränichen has been settled for quite some time.

In the 12th century Gränichen belonged to the monastery of Engelberg and later came under the reign of the Habsburgs, who passed the government of the village to the Lords of the Castle of Liebegg.

[5] The castle of Liebegg resides on a hill close to the border to Teufenthal, about three kilometers south-south-east of the village center.

Near the village center one finds the "Chornhaus", which, built in 1695, looks very similar to a small castle, because of its tower.

It is one of the main works of Protestant church building in the canton of Aargau, and is listed as a heritage site of national significance.

In order to do so, he takes care of the decisions of the assembly and the assignments imposed by the canton and the federal government.

The five municipal councils (since 1 January 2012) are: The district court of Aarau is responsible for matters of civil right.

In addition, there is also a company which fabricates heaters (Zehnder), a gravel plant and several other smaller businesses.

[12] From the 2000 census[update], 1,370 or 22.4% are Roman Catholic, while 3,619 or 59.2% belonged to the Swiss Reformed Church.

The local public rail service (AAR-Bahn), which goes from Aarau through the Wyna valley up to Menziken, has four stations: Töndler, Gränichen-Dorf, Oberdorf and Bleien.

Furthermore, there is a center for secondary education covering Realschule, Sekundarschule and Bezirksschule levels.
