Don Quixote is an epic Spanish novel by Miguel de Cervantes published in 1605. The novel is about a chivalrous madman named Don Quixote and his simple peasant sidekick Sancho Panza from the region of La Mancha in central Spain. Obsessed with the chivalrous ideals from knights doing valiant quests in the books that he has read, he decides to go on his own adventures to defend the helpless and destroy the wicked.
On their first adventure, Don Quixote mistakes a field of windmills for evil giants and attempts to fight them. From horseback he drives his lance into the revolving sail of the first windmill and is thrown from his horse and lands on the ground. When he rises up and see the windmills, he concludes that a magician must have turned the giants into windmills.
The adventures of Don Quixote and his sidekick Sancho are fictional but the windmills of La Macha are real. The actual Don Quixote Windmills that inspired this influential piece of literature are still standing and they are located in the La Mancha region of Spain.
