The Lewitz was formed, like the whole of Mecklenburg, in the last ice age. When the glacier melted it filled the Lewitz and the Stör valley with meltwater which scoured out a basin, 12,000 hectares in area. A 16 metre deep lake was formed. Later it suddenly emptied southwards. The lake became marshy and turned into peat over the course of the following millennia. Shallow waterbodies and fens (Niedermoore). In the Middle Stone Age its island-like hills, small lakes and woods offered hunters, gatherers and fishers suitable places to settle. Likewise the dried out, sandy moorlands were suitable for the arable farmers and cattle breeders of the New Stone Age. During that time several Funnelbeaker culture earthworks were constructed.
