Aiterhofen is settled since the Neolithic as the discovery of the biggest cemetery of the Linear Pottery culture in Germany showed. In 773, Aiterhofen is documented as residence of one of the Agilolfing Dukes. Around 973, another documentation as Eitarahoue. An Annalist of the 11th century falsely interpreted the name as Farmyard of Poison. The actual meaning comes from the indogermanic oid for swelling and the old high German aha for water and hof for farmyard. Therefore, the meaning of the name can be interpreted as estate at the swelling stream, which shows the reference to the Aiterach River. Approximately in the first quarter of the 13th century, the romanic parish church St. Margaretha has been constructed. Within resides the oldest bell in lower bavaria. Only the northern tower of the initially planned twin towers has been constructed. In 1883 the rococo furnishings from the 18th century have been removed. The adjacent grave yard chapel was probably constructed during the 17th century. In 1846, Angela Fraundorfer founded the convent of the franciscans of Aiterhofen, which, among other things, is aimed at the education of girls, and is operating a kindergarten, a female-only secondary school and several other facilities.
