Mährische Pforte
The Dyje–Svratka Valley has been a natural pass between the Vienna Basin (Carpathians) and the Vyškov Gate, the Upper Morava Valley, Moravian Gate and later, the North European Plain (Poland - Lower Silesia - Galicia) since ancient times. It served as an arm of several important trade routes from southern Europe to the Baltic Sea such as the Amber Road, as well as routes from Moravia to Upper Silesia and Lesser Poland.
