Climb the steep grass bank of the Kruisvest ramparts and look up at the colossal wooden blades of the Sint-Janshuismolen, silhouetted dramatically against the wide Flemish sky. Built in seventeen seventy on this high earthen embankment, this is the only windmill in Bruges that still stands on its original eighteenth-century foundation and continues to actively grind grain using only the power of the wind. The great sails span over twenty-four meters from tip to tip, fitted with heavy sailcloth canvases that can be reefed or unfurled depending on the strength of the coastal North Sea winds.

In the sixteenth century, the earthen defense ramparts encircling Bruges were crowned by more than thirty working windmills. These mills took advantage of the unobstructed coastal winds blowing off the North Sea, grinding grain into flour to ensure the besieged city could survive prolonged blockades without relying on outside bread supplies. The mill was named after the nearby Sint-Janshospitaal, which historically owned large parcels of land along the eastern ramparts and collected grain revenues to support its charitable hospital wards.

The mill is a classic wooden standerdmolen, or post mill, an ingenious marvel of traditional engineering where the entire heavy wooden body of the mill balances on a massive central oak post. The miller uses an exterior wooden tail pole and winch wheel to rotate the entire multi-ton millhouse three hundred and sixty degrees so the sails face directly into changing winds.

Climb the steep wooden exterior steps into the creaking interior, where the fragrant scent of freshly ground wheat flour fills the air. Watch heavy wooden cogwheels and leather belts turn massive French millstones, turning grain into fine baker's flour just as local millers have done since the days of Emperor Charles the Fifth. Standing on the high rampart platform beside the mill, you can look out across the broad canal below, where modern river barges glide quietly along the ancient water defenses of medieval Bruges.

Follow the crest of the ramparts southward along the tree-lined path toward the neighboring wooden silhouette of the Bonne Chière windmill.
