Windmill
Historical sources report that the Witna stream flowing out of the Great Lake was moving 4 mills. The oldest of them, mentioned already in 1298, was probably in the centre of Witnica near the pond. In the Land Book of 1337 it is written about two mills in the upper part of the river above the later iron foundry (a place known to the present day as Witnica’s POM). These mills were called Blumberger Mühle and Groβkamminer Mühle. The misunderstandings about the names, which lasted for several centuries, were resolved only after the First World War. The first mill and sawmill called Blumberger Mühle was given the name Udowald Mühle (polonized to the Gółka) and grain from Blumberg was transported to it by virtue of the mill law until the 19th century. The miller was paying 12 pieces of silver tax. The object mentioned as a mill in Blumberg was located on Witno, because in the village itself there is no mill plot, periodically the mill was under the authority of the nobility from the Kamien WIleki. Burned down in 1945.
The second mill, built by the nobility from Kamien Wielki called Groβkamminer Mühle was named Papiermühle ( Polish Szczodrak/ Ustronie Leśne ), because in the 18th century it produced paper made of old rags. In the middle of the nineteenth century it was rebuilt again into a grain mill, which was still in operation many years after 1945.
In 1809 the mill was mentioned in Blumberg without specifying its character, and at the beginning of the 20th century a motor mill called ( from the miller’s name) “Höpner Mill” was built at the western end of the village.
Immediately after the war, the mill was opened and run by Jan Niedużak for 47 years. The mill was the longest operating economic mill in the municipality. Nowadays it is in private hands waiting for renovation and change of use.
