The largest structure of the Wartburg is the Palas, originally built in late Romanesque style between 1157 and 1170.It is considered the best-preserved non-ecclesial Romanesque building north of the Alps.The Palas features rooms like the Rittersaal and the Speisesaal which have been reconstructed as closely as possible to the original Romanesque style and which contain original structures (pillars or roof elements). However, many of the rooms mostly reflect the tastes of the 19th and 20th centuries and the image of the Middle Ages prevalent at the time: the Elisabeth-Kemenate was fitted with mosaics showing the life of St. Elisabeth (created in 1902–06) on behalf of Kaiser Wilhelm II, the Sängersaal (with frescoes of the Sängerkrieg by Moritz von Schwind) and the Festssaal on the top floor. The latter also features frescoes by Schwind (on the triumph of Christianity) and served as the inspiration for the Sängerhalle at Neuschwanstein Castle.The Wartburg's Sängersaal is the setting for Act II of Tannhäuser. None of the wallpaintings, including those in the Landgrafenzimmer or the Elisabethengalerie, are actually medieval in origin, but were created in the 19th century.
