The Spanish town of Consuegra lays in La Mancha, the land of Miguel de Cervantes' Don Quijóte. The ancient Roman town called Consaburum now has a population of around 10,000 and contains a Roman aqueduct and circus. Nonetheless, the town's greatest attraction by far is its typical Manchegan look: outlined against the sky on Calderico Hill is its castle and the remains of a Moorish fortress, but more importantly, following the line of the ridge, you'll see a row of white windmills. These are exactly the windmills you want to see if you're visiting Spain after reading Cervantes' literary masterwork.
One of the windmills is open to the public, but the outside view is much more enchanting. From the top of the hill, you can look down on the rooftops of the town, while spreading before you is the infinite horizon of La Mancha. The castle was built by order of the Knights of St. John in the 12th century, after Consuegra had been named the Priory See of the order.
Travelling from Madrid to Sevilla over the highway, you'll automatically pass Consuegra, recognizable from quite a distance on your right by the row of windmills on the hill.
