Originally a naval base, Comagena, and later a center for the Babenberg dynasty, Tulln is one of the most ancient towns in Austria. Located on the right bank of the Danube, it is called "the flower town" because of the masses of blossoms you'll see in spring and summer. It's the place, according to the saga of the Nibelungen, where Kriemhild, the Burgundian princess of Worms, met Etzel, king of the Huns. A well-known "son of Tulln" was Kurt Waldheim, former secretary-general of the United Nations and president of Austria, who was plagued by his past Nazi affiliations.
