Usadelsche Mühle (Nuns' Mill). The small watermill was first mentioned at the ceremonial inauguration of Wanzka Monastery in 1290, making it one of the oldest mills around Neustrelitz. As part of the ceremony, the sovereign, Margrave Albrecht of Brandenburg, issued a charter of foundation. "The monastery was dedicated to the village of Wanzka, with 25 hectares of land in Ballwitz, the villages of Blankensee, Zachow, Krickow, along with the mill and Mechow." The mill "along with Krickow" referred to the mill later known as the Nonnenmühle.
Today, the remains of the old watermill, the weir, and the stable barn are still preserved and protected as monuments. The mill property is privately occupied, and the owner began renovating the old fieldstone walls in the summer of 2020.
Around 1999, the State Office for Environment and Nature (STAUN) commissioned the engineering company for water and waste management, environmental technology and infrastructure (ign) to plan the "reconstruction of the weir with fish ladder at Nonnenmühle" (ign 2000a). The owner at the time, Mathias Stinnes of Neubrandenburg Transport AG, intended, in coordination with this measure, to "restore the mill pond so that it can be used as a water reservoir for a water wheel to be built" (Stinnes 2000). IGN was commissioned to plan the project. Since the measure represented an intervention in nature, STAUN was commissioned to assess and, if necessary, approve the measure (Stinnes 2000). According to ign, the cost estimate for the reconstruction of the mill pond with water wheel was around 316,000 DM. Of the original water surface, which was around 4,700 m², around 2,200 m² were to be restored. Concrete elements that were built when the mill was fitted with the power turbine were also to be dismantled (cf. ign 2000b). The renovation plans developed for the mill pond and the new construction of the water wheel were examined by the STAUN and, in accordance with §§15 and 18 of the State Nature Conservation Act, did not represent interventions that could be approved on the planned scale (ign 2000c) and were never implemented. No lasting negative consequences for nature were expected from the construction of the fish ladder together with the dismantling of the weir system and the measures could be implemented (ign 2000c).
Today, the remains of the old water mill, the weir and the stable barn are still preserved and protected as monuments (MSE district 2021). The mill property is privately inhabited and the owner began renovating the old fieldstone walls in the summer of 2020.
