where did the author write man of la mancha?

Miguel de Cervantes is believed to have conceived and begun writing "Don Quixote de la Mancha" while imprisoned in the cave of Medrano (also known as the casa de Medrano) in Argamasilla de Alba, Spain. This cave, said to be Cervantes' prison, is traditionally considered the place where he started the famous novel. The first part of "Don Quixote" was published in 1605, and its story is set in the La Mancha region of Spain, though Cervantes deliberately left the exact village unnamed in the text.
