It was mentioned again in 1280 during the Wittelsbach Dynasty with the name 'Vornolzhusn'.Merkur.de - Blick auf 1000 Jahre: Von Varnoleshusa zu Fahrenzhausen. https://www.merkur.de/lokales/freising/freising/fahrenzhausen-ort88182/blick-auf-1000-jahre-von-varnoleshusa-zu-fahrenzhausen-13531956.html A local Catholic church was first mentioned in 1315.
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.Christian Pantle: Der Dreissigjährige Krieg. Als Deutschland in Flammen stand. Propyläen Ullstein Buchverlage GmbH, Berlin 2017, , S. 128 ff.
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. They were en route to fight at the Battle of Landshut and the Battle of Eckmühl in April 1809.K.K. Generalstab (Hrsg.): Der Feldzug des Jahres 1809 in Süddeutschland.

On June 25, 1844, a violent hailstorm destroyed all crops in Fahrenzhausen and neighboring villages. 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. The procession has taken place every year ever since, including during the two World Wars. It only had to be canceled in the Corona years 2020 and 2021.Hans Schertl, "Kirchen und Kapellen im Dachauer Land. (German webpage) http://kirchenundkapellen.de/kirchen/fahrenzhausen.php

Fahrenzhausen has two sports clubs: FC Ampertal Unterbruck, and Spielvereinigung Kammerberg.
Unterbruck Unterbruck, just 1 Kilometer south of Fahrenzhausen, is situated directly on the Amper River. Because of this, a bridge was built as early as the 12th century so that mail and carriage traffic can go either south to Munich or north to Ingolstadt. Later on it became a toll bridge. Unterbruck also housed a post office, an inn, and a sawmill.
During the War of the Austrian Succession,(1740–1748) the bridge at Unterbrück was burned down in 1745 in an attempt to halt the Austrian advance.Das Betrangte und nunmehro Von Herrn Grafen Saint Germain Obristen Uber des Graf Oettingischen Dragoner-Regiment, Erlößte München. Riedlin, München 1745.
Unterbruck is also known for its red-brick, neo-gothic chapel (St. Anna), built in 1859.Filialkirche St. Anna in Unterbruck. https://kirchenundkapellen.de/kirchenpz/unterbruck.php
