was refurbished from the late 19th century onwards and became a major tourist attraction with the Festungsbahn funicular railway, opened in 1892, leading up from the town to the Hasengrabenbastei; It stands today as one of the best preserved castles in Europe. During the early 20th century it was used as a prison, holding Italian prisoners of war during World War I and Nazi activists before Germany's annexation of Austria in March 1938. German ceramicist, sculptor and painter Arno Lehmann lived and created in Hohensalzburg Fortress from 1949 until his death in 1973. Hohensalzburg Fortress was selected as main motif for the Austrian Nonnberg Abbey commemorative coin minted on April 5, 2006. This was the first coin of the series "Great Abbeys of Austria". It shows the Benedictine convent of Nonnberg Abbey. In the hilltop on the background, the fortress and the Kajetaner church can be seen. Also in 1977 the Austrian Mint issued a coin for the 900th anniversary of Hohensalzburg Fortress. Interior The fortress consists of various wings and courtyard. The Prince-Bishop's apartments are located in the so-called "Hoher Stock" (high floor). Salzburg Bull The Krautturm houses a large aerophon of more than 200 pipes which is called the "Salzburg Bull" (Salzburger Stier). This huge mechanical organ was built in 1502 by Archbishop Leonhard von Keutschach. It was renewed by Rochus Egedacher in 1735. From Palm Sunday to 31 October the "Salzburg Bull" is played daily at 7, 11 and 18 o'clock. The aerophone thus initiated the playing of the carillon at the Residenzplatz and ended it again. One of Austria's most famous cabaret groups is named after it. Golden Hall Starting in 1498, Archbishop Leonhard von Keutschach had the magnificent state apartments installed on the third floor. The rooms in which the archbishops would normally have lived were one floor below. The state apartments were primarily used for representative purposes and for festivities. The Golden Hall was richly decorated and indicates that the fortress served the archbishops not only as a refuge in times of crisis, but frequently also as a residence up to the 16th century. In order to gain more space, Archbishop Leonhard von Keutschach had four massive marble pillars constructed on the right-hand outer wall and had a loggia added on. As in the other rooms the ceiling is coffered, each coffer being adorned with gold buttons symbolising the stars in the sky. The
