Occurrence Sentence Text Source
The Beemster is the first so-called polder in the Netherlands that was reclaimed from a lake, the water being extracted from the lake by windmills.
In the period 1150-1250 peat-digging by people, and storm floods, enlarged that small river into an inland sea, a lake in open connection with the Zuiderzee.
Around 1605 private investors started to drain the Beemster lake.
In 1610, this was almost complete, but the lake re-filled because of a break in the Zuiderzee dikes.
It was created by the draining of Lake Beemster in 1612, in order to develop new agricultural land and space for country residences, and to combat flooding in this low-lying region.
The polder itself followed the outline of the lake, and the direction of the squares corresponds as much as possible with the former shoreline, so as to avoid creating unusable lots.
