Zwei Herren von Wädenswil und die Wasserwirtschaft der Mönche von Interlaken | Two lords of Wädenswil and the water resources management of the monks of Interlaken

In 1257 the lords of the castle of Unspunnen granted the monks of Interlaken the right to build protective works against the floods of the torrent Lütschine and to divert some of its water to the monastery. The corresponding charter belies a widespread legend, which attributes to the monks a real correction of the Lütschine.
