Bishop Soboto of Augsburg incorporated Heretsried to Kloster Holzen in 1242.

When the peasants' war began around 1525 the peasantry of Heretsried didn't oppose the monastery of Holzen.

In 1636 in time of the thirty years' war, the church and the citizens' houses were burned down by the Swedish troops.

The chronicle of Holzen is telling about abbess Agnes von Neuegg who found only 6 survivors in Heretsried.

When in 1805 Napoleon I. fought a war against the Austrians, there were three French horseman shot by peasants who took the stolen money which came from nearby in a forest near Heretsried.
