Kłodzko Valley
The shortest (and possibly oldest) road avoids alpine areas and led from the Baltic coastline (nowadays Lithuania and Poland), through Biskupin, Milicz, Wrocław, the Kłodzko Valley (less often through the Moravian Gate), crossed the Danube near Carnuntum in the Noricum Province, headed southwest past Poetovio, Celeia, Emona, Nauportus, and reached Patavium and Aquileia at the Adriatic coast. One of the oldest directions of the last stage of the Amber Road to the south of the Danube, noted in the myth about the Argonauts, used the Sava and Kupa rivers, ending with a short continental road from Nauportus to "Tarsatica" (Trsat, Rijeka) on the coast of the Adriatic.
