The oldest trace of a settlement is in Brühl, where the ruins of a Roman era settlement were found. By the 13th-14th century a number of Bernese patrician families owned land and rights in the village and surrounding farms. One of the landowners was Anna Seiler, who established a hospital in Bern and in 1354 willed her landholdings to support the hospital. Today she is remembered with the Anna Seiler Fountain in Bern. In 1343, the von Blankenburg family donated Kirchenthurnen and the surrounding land, which probably included Lohnstorf, to Interlaken Abbey. In 1528 Bern accepted the new faith of the Protestant Reformation and forcibly secularized the Abbey and its lands, including Lohnstorf.
