The city of Dürnstein and Dürnstein castle ruin are connected by a wall. The castle was built between 1140-1145 by Hadmar I Kuenring and blasted by Sweden under General Torstenson in 1645. You can see a model of the city and the ruins at Dürnstein Abbey.
Dürnstein castle is known from the legend about Richard the Lionheart. The legend tells, that the English King Richard the Lionheart tore up the Austrian flag on the return journey of his crusade and refused to share the spoils of war with Leopold V. Sure, Leopold V. held the English king in the castle 1192-1193. The Royal prisoner could receive travelling singer (troubadours) for his entertainment, resulted in probably later the legend of Blondel singer. His faithful minstrel moved from Castle to Castle, until he discovered his King in Dürnstein, by singing a song verse, the prisoner added. Richard the Lionheart was released after a ransom of 150,000 Silver marks in freedom.References:
The Erfurt Synagogue was built c. 1094. It is thought to be the oldest synagogue building still standing in Europe. Thanks to the extensive preservation of the original structure, it has a special place in the history of art and architecture and is among the most impressive and highly rated architectural monuments in Erfurt and Thuringia. The synagogue was constructed during the Middle Ages on the via regia, one of the major European trade routes, at the heart of the historical old quarter very close to the Merchants Bridge and the town hall. Many parts of the structure still remain today, including all four thick outer walls, the Romanesque gemel window, the Gothic rose window and the entrance to the synagogue room.
After extensive restoration, the building was reopened in 2009. On display in the exhibition rooms is an collection of medieval treasures discovered during archaeological excavations. This includes 3,140 silver coins, 14 silver ingots, approx. 6,000 works of goldsmithery from the 13th and 14th centuries and an intricately worked wedding ring of the period, of which only two others are known to exist anywhere in the world. A mikveh (Jewish bath) has been excavated close by (13th/14th century). The Old Synagogue, the Small Synagogue and two Jewish cemeteries together form a network of historical buildings and sites which vividly portray the role of Jewish life in the history of Erfurt.
