Wehrmühle Biesenthal, Historic watermill in Biesenthal, Germany.

Wehrmühle Biesenthal is a former watermill on the Finow, about 1.5 km north of Biesenthal's centre. The mill building burned down on 23 August 2002; what remains is the old administrative building, converted into a villa with a stucco facade in 1907, plus a storage shed built around 1870. The rear part was rebuilt by 2006.

First recorded in 1375 as Werremole, the mill's name refers to a Landwehr: in times of danger the Finow was dammed until the area around the castle on the Schlossberg was flooded, leaving only the castle dry. The surviving administrative building was converted into a villa with a stucco facade in 1907 by the Jewish entrepreneur Mühsam; the mill burned down on 23 August 2002.

The site functions as an art venue where exhibitions and events showcase work from local and international creators. Visitors experience the space as an active gathering place for contemporary artistic practice.

The site is accessible by public transportation and offers on-site accommodation, dining, and workspace options. Visit times are flexible as exhibitions and events run throughout the year.

The mill's Francis turbine survived the 2002 fire and was renovated in 1989; in 2010/11 a bed ramp replaced the old turbine installation to restore ecological continuity of the Finowfließ. The turbine and some other parts remain preserved as a monument.
