The Wartburg is a castle originally built in the Middle Ages. It is situated on a precipice of 410 metres (1,350 ft) to the southwest of and overlooking the town of Eisenach, in the state of Thuringia, Germany. It was the home of St. Elisabeth of Hungary, the place where Martin Luther translated the New Testament of the Bible into German, the site of the Wartburg festival of 1817 and the supposed setting for the possibly legendary Sängerkrieg. It was an important inspiration for Ludwig II when he decided to build Neuschwanstein Castle.

Eisenach is a town in Thuringia, Germany with 42,000 inhabitants, located 50 kilometres west of Erfurt, 70 km southeast of Kassel and 150 km northeast of Frankfurt. It is the main urban centre of western Thuringia and bordering northeastern Hessian regions, situated near the former Inner German border. A major attraction is Wartburg castle, which has been a UNESCO World Heritage Site since 1999.
