Where did Friedrich Nietzsche spend the final years of his life after his mental breakdown?

After suffering a mental breakdown in Turin, Italy, in January 1889, Friedrich Nietzsche spent the final 11 years of his life in a state of total mental incapacity.12

Following his collapse, he was initially treated in an asylum in Basel, Switzerland. He was subsequently moved to Naumburg, where he remained under the care of his mother. After his mother’s death in 1897, he was moved to Weimar, where he spent his remaining years under the care of his sister, Elisabeth Förster-Nietzsche, until his death in 1900.2
