The first legal proof of Lungern's existence is contained in a tax register for the diocese of the bishop of Konstanz in Germany dating from the year 1275. It is mentioned as
Lutigern and also as
de Lungern. In 1861 it became easier to reach the village with the construction of the old road over the
Brünig pass. A quarter century later, in 1886, the first
mail carriages came over the pass. However, this only lasted two years, in 1888 the railroad from
Brienz to
Alpnachstad (now part of
Alpnach) opened. In 1887 the Eibach river flooded causing damage to the old village church. Six years later, in 1893, was the consecration of the
neo-gothic style church. At the end of the 18th century the population of Lungern lowered the level of the lake, with great effort and over many years, in order to improve living conditions. The works created new land for agriculture, housing, and a sawmill. Within 80 years the hard-won land was lost to a new dam: in 1922 a company named CKW built and started running a power station located at the lake. Nowadays the local power station (EWO) produces electricity from the power of the water of the Lungerersee. In 1942 the railroad line over the Brünig pass was electrified. ==Population and economy==
