By mounting the body this way the mill is able to rotate to face the wind direction an essential requirement for windmills to operate economically in north-western Europe where wind directions are variable. When the blades are stopped in an "X" configuration, the windmill is closed or not functional. In the fourteenth century, hollow-post mills were used to drive scoop wheels to drain the wetlands.
