The Vier Winden is a 1776 stage mill on the Rotte River in the Rotterdam neighborhood of Terbregge. The mill was used to grind grain until 1964. Today the mill on the Terbregse Rechter Rottekade is out of operation but rotary. Now it houses the Three Color Gruttery, a company that has or gets everything for YOU to bake yourself for the individual based on an experience from father to son.
