Regenstein Mill

The Regenstein Mill (German: Regensteinmühle) was a water-powered corn and oil mill below Regenstein Castle north of the town of Blankenburg (Harz) in the county of Harz (Saxony-Anhalt).

The mill was built in the first half of the 12th century in order to supply the castle and its outlying estate of Nienrode.

Between 1988 and 1991, work was carried out to uncover this channel over a length of about 500 metres.

The Regenstein Mill was in operation until the end of the Middle Ages and then increasingly fell into rack and ruin.

In 1758, during the Seven Years' War, the remains of the mill were demolished by the Prussians for strategic reasons as it lay closeto the border between Brunswick and Prussia.
