Fahrenzhausen has several villages in its community: Appercha, Bachenhausen, Bergfeld, Grosseisenbach, Grossnöbach, Jarzt, Kammerberg, Lauterbach, Unterbruck, Viehbach and Weng.

[7] Fahrenzhausen and the surrounding villages were most likely affected during the Thirty Years War, particularly during the Swedish march to Munich in 1632, or even the French attack in the Freising and Dachau area in 1648.

[8] During the Napoleonic Wars, French and Bavarian troops marched from Munich along the Isar towards Freising and Landshut, perhaps some units passing through the Fahrenzhausen area.

The next morning, the catholic faithful made a procession march from Fahrenzhausen to nearby Westerndorf, petitioning and praying to be spared such terrible storms in the future.

It only had to be canceled in the Corona years 2020 and 2021..[11] Near the end of the Second World War, units of the U.S. Army passed through Fahrenzhausen and the surrounding areas in late April 1945, shortly before the liberation of Dachau and Munich.

[15] Second oldest business is the Backery Kistenpfennig, founded over 50 years ago in Fahrenzhausen and now has over 20 bakeries all over the greater Munich area.
