The yellow engraving is one of the many beautiful "holes in the earth" in the area.
With the growth of the nearby city of Berlin, the rich clay deposits
in the Ketzin area gained great economic importance.
By 1881, 15 efficient brickworks had been established there. Approximately
100 million bricks were fired annually, mostly transported to Berlin by ship.
From 1900 onwards, the boom declined and collapsed completely in the 1920s.
In 1946, the last brickworks had to close. Clay mining left many of the so-called "holes in the earth," which filled with groundwater and are now part of this beautiful natural landscape.
