De Roos

De Roos, also locally known as Roosmolen or Koren op de Molen, is a wind and platform mill situated within the municipality of Delft, in the South Holland province of the Netherlands.

The mill was originally constructed on the southern city wall of Delft but was later relocated and rebuilt above the western fortifications of the Dutch municipality in 1679. Two principal phases of implementation of the Delft mill followed this reconstruction. The first was dated 1728, while the second was from the 1760s. The building has been the subject of multiple restoration projects, commencing in the late 1920s and concluding in 2023. The artistic work, whose historical background remains largely uncharted before its 1679 reconstruction, represents the sole surviving mill within the erstwhile fortified zone of Delft, among the eighteen that previously operated within the Dutch city.
