A 'smock' windmill. Inside, the mill drove three pairs of millstones, the two larger pairs being of 4 feet 6 inches (1.37m) diameter.
Wicken Corn Mill is a large windmill with many characteristic Cambridgeshire features.
- The tarred tower carries the white domed cap with its vertically boarded roof.
- The cap carries the four large sails of 63 feet (19.2m) overall span and 9 feet (2.74m) width.
- The sails open to spill the wind and control the power according to Cubitt's patent of 1807.
- The cap and sails are turned to face the wind automatically by the blue fantail, a small wind rotor set above the rear of the cap.
