Calbe is a town in the district of Salzlandkreis, in Saxony-Anhalt, Germany.GeographyIt is situated on the Saale River, approx. 12km north of Bernburg, and 25km southeast of Magdeburg. It is known as Calbe an der Saale, to distinguish it from the smaller town of Kalbe on the Milde in the same state. Pop. (1905) 12,281.It is a railway junction, and among its industries are wool-weaving and the manufacture of cloth, paper, stoves, sugar and bricks. Cucumbers and onions are cultivated, and soft coal is mined in the neighborhood.The town has a statue of Roland outside its city hall. Roland is a symbol who represents many small and medium-sized towns in Saxony-Anhalt, symbolising free trade and prosperity. The town also has a very old church, and a tower known as the "Hexenturm" ("Witchtower"), in which the townspeople imprisoned accused witches and tortured them in the Middle Ages.The river Saale runs on the east side of the town, and over a weir. This is a small kind of dam where the water flows over the structure allowing passage of shallow draft barges up or down — moreover rather than being channeled through it the water is used off this flow to generate energy and it raises the water level only a relatively small amount.At the weir the Saale is partly diverted, while some of the river flows over the weir and continues on its natural path, the rest is channeled through an artificial path, known as "Mühlgraben". This takes the water between two (now abandon) buildings which used to harness the power of the water to mill grain into flour, and the other to make paper. After flowing between the mills the water continues on an artificial path for a couple of miles before returning to the Saale proper.
