Only at the turn of the old and new era, so during the period of Roman influence, settlement began to press into the mountain valleys, which was associated with the development of trade. These areas were inhabited by the pre-Slavic population, which, after the migration of peoples, developed in the early Middle Ages Slavic tribes. A conviction has become established, that the area up to the Karkonosze was inhabited by Bo-barbers, but it is a concept that has been questioned by many researchers, who believe, that the Bobrzanie had their seats (if at all) much further north, over the middle Bóbr, and here they could possibly reach Bieżuńczanie from the west, and from the east, Trzebowianie, but most likely the Karkonosze Mountains remained uninhabited.

It can therefore be assumed, that the Karkonosze region remained uninhabited until the 10th-11th centuries., when the foundations of the Polish state began to take shape. At that time, their area belonged to the Wleń castellany, thus the administrative center of the region was quite far to the north. And it is with the castle in Wleń that the oldest known road crossing the Karkonosze is connected – Czech Path, which led from the Kamienna valley, from the mouth of the Kurzacka Struga, to the sources of the Elbe and on to Bohemia, in the Rokytnice nad Jizerou district. Undoubtedly, the older and more busy crossing was the Lubawa Gate at the eastern end of the Karkonosze Mountains, which is fully understandable, taking into account the availability of the area and the villages lying on that route for centuries. To the equally old ones, maybe even older connections were Babia Ścieżka, constituting a fragment of the later Silesian Route, partly used by the completely contemporary Silesian Road. It led to Dobre Source near Grabowiec, considered a local pre-Slavic cult center, and then to Równia under Śnieżka (the source of the White Elbe) and further to the Vrchlabí region.

Further passes through the Karkonosze Mountains, but later, functioning only from the end of the Middle Ages, former: Okraj Pass – connecting mining Kowary with mining Svobodou nad Upou, Customs Road through the Karkonoska Pass and Szklarska Road connecting the steel mills in Szklarska Poręba and Harrow (the latter actually gained importance only in the 18th century.).

Following the course of the oldest roads through the Karkonosze Mountains, can be seen, that, unlike most mountain ranges, they did not cross the ridge with passes, that is, in places that seem naturally most accessible. After all, and the Czech Path, and Babia Path (hereinafter the Silesian Route) they did it in seemingly random places, and yet justified. The Bohemian Path led to the source of the Elbe and further along the river – and the mountain ridge in that area was not forested, it was above the upper edge of the forest, similarly to Równia pod Śnieżką, while the Karkonosze passes were then hidden in forests and almost invisible from below. Szklarska Droga is the best proof here, which overlooked the slopes of Wysokie Grzbiet in the Jizera Mountains, and she descended to Harrachov, defeating the swift Jizera. The Szklarska Pass was not yet known as a more convenient passage in this area.

The situation was similar in the eastern part of the Karkonosze Mountains, where Stara celni cesta enters the Lasocki Ridge from the Czech side, and further south leads the Old Iron Cesta. They are the traces of former connections of mining centers on both sides of the border.

Besides, communication through the Karkonosze Mountains was poor then, and contacts on both sides – faintly. In fact, from the very beginning, the border was established on the ridge of the Karkonosze Mountains: first between Poland and the Czech Republic, then the Duchy of Świdnica and Jawor and the Czech Republic (functioning even then, when it became part of the lands of the Czech Crown and the Habsburg monarchy), then Prussian-Austrian, German-Czechoslovakia and again Polish-Czech. The border was permanent and, apart from minimal corrections, has not changed in this region over the centuries. The main trade routes avoided the inhospitable wilderness from a distance. Disputes continue to this day, or prince Bolesław Krzywousty, leading in 1110 r. a retaliatory expedition in the Czech Republic, he crossed the Karkonosze Mountains or passed the Lubawa Gate. This passage is described by Gall Anonymous in his Chronicle, but in such an enigmatic way, that you cannot find out the truth.

This one example already proves it, that at the beginning of the 12th century. there were no frequented passages through the Karkonosze Mountains, and exceeding them was a peculiar phenomenon. Including the description of this event in the Chronicle of Gallus Anonymus made it an important fact, equal (on our scale of events, of course) Hannibal's crossing of the Alps.

Jelenia Góra already existed at that time, although in a slightly different place, possibly also Kowary, but the oldest villages at the foot of the Karkonosze Mountains (Sosnowka, Podgórzyn, Piechowice, Miłków, Miszkowice) appeared at the earliest at the end of the 13th century. You have to remember the rest, that the first settlements were small and lower than the present ones, in the Jelenia Góra Valley. Only later, as it develops, pressed into the Karkonosze through the valleys of streams.

Therefore, it must raise doubts quite commonly, and perhaps too uncritically the story of Good Spring and the chapel above it, which allegedly was built at the turn of the 12th and 13th centuries., which was supposed to be attested by the date on the altar that no longer exists. At that time, there were no settlements in the area yet, a te, that existed, did not have churches. The network of rural parishes in Silesia did not develop until the beginning of the 14th century. So, where would a chapel be built in such a remote and uninhabited place and who would operate it?? The accounts of its creation at the beginning of the 13th century are not very certain., and some only after the Hussite wars, so around the middle of the 15th century.
