Wartburg Castle
From May 1521 until March 1522, Martin Luther stayed at the castle, after Frederick the Wise had him taken there for his safety. This was after Luther's excommunication by Pope Leo X and his refusal to give up his beliefs at the Diet of Worms. During this time, Luther translated the New Testament into German. It was not the first German translation of the Bible but it became the most well known and most used.
