As boats sail west on the Danube River, from the Austrian city of Vienna, they stop at some of the most magnificent monasteries in Europe. The abbeys at Melk and Klosterneuburg are two of the most famous. Klosterneuburg has been home to a group of Augustinian clergy for over 900 years and contains the Verdun Altar, which is one of the world's most important medieval works of art. Melk was founded as a Roman garrison and became the cradle of Austrian history. Its library contains hundreds of colorfully illustrated books and was probably the inspiration for Umberto Eco's medieval murder mystery, "The Name of the Rose". It also has the only working model of a reusable coffin that was promoted by the King of Austria. Burt Wolf tours both monasteries and stops for lunch at the restaurant of one of Europe's most talented women chefs.
