Wartburg College takes its name from the Wartburg Castle in Eisenach, Germany. During the stormy days of the Reformation, the castle served as a refuge for Martin Luther. Under ban by the emperor, Luther spent 10 months in hiding at the castle, disguised as a knight. During that time, he completed a translation of the New Testament into the language of the common people. His work is credited with helping to unify the country by providing a standard for written German. Today, ties between Wartburg College and the Wartburg Castle have been enriched by a Sister City relationship between Waverly and Eisenach and by a formal agreement between the college and the Wartburg Castle Foundation.
