Archeological researches along the Vistula ond Odra rivers route, have been carrying out since the second half of the eighteenth century. At first the researches were done by an accident but since the twentieth century they have been done more systematically and professionally. Nowadays, there are 5000 archeological excavation sites along the Vistula ond Odra rivers route, which represent all the settlement phases from the declining years of the Ice Age till the Middle Ages. Most of them are distinctly seen in the landscape. Unfortunately, only a small numer of them have been signed for tourists.
