The Nietzsche-Haus in Naumburg, Germany, is a building dedicated to the life and work of the German philosopher Friedrich Nietzsche. In the summer of 1858 Nietzsche's mother, Franziska Nietzsche, moved with her two children, Elisabeth and Friedrich, to 18 Weingarten in Naumburg, the site of the Nietzsche-Haus. She rented a bright, spacious apartment on the upper floor. In 1878 she bought the house and continued to live there until her death in 1897. Since 1994, the Nietzsche-Haus has been open to the public as a museum. In October 2010, the Nietzsche Documentation Centre opened, dedicated to research into and critical engagement with Nietzsche.
