The castle and the windmills are Consuegra's most important monuments. Most Spanish windmills, like those described in Cervantes's Don Quixote, can be found in the province of Castilla-La Mancha in central Spain. The best examples of restored Spanish windmills may be found in Consuegra where several mills spike the hill just outside of town, giving us a spectacular view of the 12th century castle and of the town. The castle was once a stronghold when Consuegra was the seat and priory of the Knights of San Juan, the Spanish branch of the Knight's Hospitallers of the Order of St. John of Jerusalem. Windmills are also located in Mota del Cuervo, Tomelloso, and Campo de Criptana. Consuegra is famous due to its windmills. They became famous in the 16th century, when Don Quixote was first published.. The introduction of the windmills was made by "Caballeros Sanjuanistas", who brought these machines that helped millers. These machines used the wind to grind grain (the most common grain is wheat). The windmills were transmitted from fathers to sons. They usually consisted of two rooms or levels. Millers had to carry sacks of grains that could weigh 60 or 70 kilos to the top floor, they rotated the sails of the windmill as the top part of the windmill or dome was moveable. They stopped being used at the beginning of the1980s.
