Frohburg Castle Ruins
Highlight • Castle
The castle ruin is classified as worthy of national protection, and is therefore at the highest level of monument protection awarded in Switzerland.
The place was populated as early as the Bronze Age and then again during the Roman period. In the 10th century, an important noble family in the Olten and Zofingen region settled on the Jura ridge. In the immediate vicinity of the castle, the castle and followers of the castle lords opened up new settlement land by clearing. The family has appeared in the documents as the Counts of Frohburg since the late 11th century. The family derived its name from the castle name. It dominated a large area of influence between the Aare and the Rhine in the old regions of Aargau, Buchsgau and Sisgau until the 14th century.
After a first modest settlement with wooden houses, the counts erected a large number of larger structures within the surrounding wall of the castle over the centuries. In addition to a count's house, service buildings and workshops were also part of the assembly. Of particular interest is a small smelting plant for iron, which was exploited as an important natural raw material in the Jura. In addition, the processing of leg has been proven to be another specialty trade. The castle had at least three water cisterns.
In the course of the 14th century, the Counts of Frohburg lost their privileged position, and the individual buildings in the family's ancestral castle were abandoned over time. When the counts died out around 1367, there were probably no more permanent residents in the complex, which has since fallen into ruin and has been used as a stone supply by residents of the agricultural settlements in the area.
First investigations of the site before the middle of the 20th century and scientific excavations after 1970 provided rich information about the settlement history of the castle.
A detailed Germanic investigation carried out with the archaeological studies has shown that the castle name really means «Frohburg». This is how the place was called in the area until the early 20th century, and only in later decades did the incorrect spelling Froburg spread here and there due to an incorrect approximation of the name to the Old High German word group of fro (= Herr).
Today the facility is one of the popular tourist destinations in the Olten region.

Erlinsbach AG
Highlight • Settlement
The Aegean Erlinsbach borders on the city of Aarau, but not on the Aare Canal. Also Erlinsbach SO extends to the Aarauer city boundary. On the other side Erlinsbach has a promontory up to the highest point of the canton of Aargau, the Geissfluhgrat at 908 m above sea level.
Several times changed the valley in the episode their owners, ultimately, the monastery Königsfelden was the largest landowner in Erlinsbach. After the conquest of today's Aargau by Bern, this brought 1528 also in the possession of the goods of the monastery. Berne went to the Reformation and divided the people left of the Erzbach Kirchberg Kirchberg. The then Solothurn part of the valley remained with the Catholic faith. Since the only Erlinsbacher church was on Solothurn soil, disputes between Bern and Solothurn for the use of the church Niedererlinsbach was not lacking.

Winznau Cultural Trail
Highlight • Trail
As a result, the culture path does not have a chronological course. Thus, in addition to the data on the history of the Rankwog Bridges, there is a historical event that dates back 10'000 years and points to the first people in the community who lived in the Käsloch and Köpfli. This requires the reader to be able to change, but also has the advantage that one can leave the track at any time or "get in" at the Giessen Bridge, the middle bridge or the arch bridge in the oak forest. The respective location is marked with a red dot and shows the further course. The realization of the cultural path has been made possible by the former inhabitant of Winznau, Mrs. Gret Flückiger-Hulliger. On the occasion of her demise she set up a foundation for the promotion of cultural life in Winznau. Ernst Sturzenegger, Winznau, and the lottery fund of the canton of Solothurn also contributed. The Aare-Tessin AG has granted the permission for the establishment of the cultural path. We all thank you.

Impressive large ruin with many fireplaces. If you are sure-footed and have a head for heights, you can climb the tower, which offers a wonderful view. The ascent is on a steep path in the rock with a wire rope as an aid.

An extremely suitable starting point (free parking and public transport) for wonderful hikes to the highest point in Aargau, Geissfluegrat, even with a summit book, or in the other direction to Wasserflue with a fantastic view. You can cross three cantons here with little effort. If you can, you should avoid weekends and public holidays. There are a lot of people on the road and the motorcyclists are a particular nuisance, racing up and down the road at extremely high speeds and with a noise like that at the Nürburgring. "Safety first" is literally a foreign word for some people.

At the weir, most people drive over the new weir bridge in the direction of Schönenwerd. Tip, coming from Aarau, drive over the bridge on the right and immediately after the bridge turn left. Now always straight ahead along the Aare. There are almost no pedestrians or bikers here. Beautiful drive through the forest to Schönenwerd, right in the center.
