The history of Abtenau begins with the settlement by the Bavarians in the 6th century AD and the Christianization by St. Rupert around 700.
The name Abtenau was first recorded in a deed of donation from 1124 kept in the archives of St. Peter's Abbey (Salzburg); At that time, Archbishop Konrad 1 donated some land to the monastery, which also included the Lammertal. The St. Peter Monastery still owns forest and agricultural areas in the Lammertal today.
Since the 12th century, St. Peter promoted the settlement of the Abtenau Basin. The first Abtenau church was built in the second half of the 12th century by Archbishop Konrad 3.
During the feudal period of the 14th and 15th centuries, the Lammertal was already well organized with around 200 inhabitants; There has been evidence of land and land judges in Abtenau since 1332.
The Lammertal does not appear to have been involved in the peasant uprisings of 1462, and it was spared from the peasant wars that followed.
In 1507, Abtenau, now a small rural center in the Lammertal located around the mother parish, was made a market by Leonhardt von Keutschach, Archbishop of Salzburg, and thus received market rights and civil liberties such as buying, selling, trade and commerce as well as the right to do so every year to be able to hold a fair on Maximilian Day.
several beer and wine taverns that were opposite the church district. This division still exists today. On one side of the market square are the church, rectory and cemetery; There are five inns diagonally opposite.
The beginning of the school system in Abtenau dates back to the year 1600 and, like everywhere else, had its origins in the reading of Holy Scripture and - after the Council of Trent - the catechism.
On August 1, 1850, a postal expedition with driving mail was set up in Abtenau
After the Second World War, the development of tourism began with the so-called summer resort; With the further development of alpine skiing, the winter season later became more important. Today Abtenau is the largest town in the Lammertal with around 6000 inhabitants. It has retained its rural and down-to-earth character and is therefore popular with holiday guests.
