The Lake Arendsee, like it is today, appeared in 1685
after saltmines had collapsed. The biggest lake of this kind in northern
Germany has a surface of 5,54 m/2. It is 50m deep at the deepest point
and 30m in other areas.
After the collapse of the saltmine, 40 ha land disappeared and the mill
of arendsee was hereby destroyed. The millstone was brought back up in
1982 and can be seen at the historical museum of Arendsee. The water of the lake is of superior quality and in combination with
the fine sandy beach it just right for swimming, diving and relaxation.
