The major transport routes, both by rail and by road, can be reached easily in a very short time. It is therefore not surprising that Biberstein has increasingly become an attractive residential community in the Aarau region.

Highlight • Castle

The ruin Horen, often referred to topographic maps with Burg Rosenberg, is the ruin of a hilltop castle above Küttigen in the Swiss canton of Aargau. It is located at an altitude of 450 meters on a foothill of the Kirchberg about 500 meters northwest of the church and belongs to the type of hill castles (moth).

Neither the builders nor the exact year of construction of Horen Castle are known, but archaeological research has shown that the ruin was settled in the 12th century. At that time, the plant existed next to an oval Bering with gatehouse only from a residential tower. The area was secured by a neck trench to the southeast. Already around 1200, the castle was abandoned. The last owners were the canons of Münster.

Pfadihaus Gränichen

Highlight • Mountain Hut

Thepfadihus is a good starting point for many bike tours in the forests of Gränichen. Immediately in the forest after the path hike there is a steep trail on the left to the fireplace in the winter hole. The path straight across the Fuden to the Zehnderhüsli is particularly recommended.

The once mighty ruins of Urgiz stood in the middle of the rocky outcrop and are still surrounded by 4 moats, some of them mighty. There are still traces of the keep, the corner tower and the lower outer wall. Further information can be found on the detailed information board.
