Already 12,000 years ago, gatherers and hunters used the protection of the caves in Chessiloch.

Very interesting cave in which numerous archaeological finds from prehistoric times (Magdalenian culture, Neanderthals, Paleolithic) were made.

The Ermitage is a large and lovingly designed green area from 1785, with three idyllic ponds, several romantic grottos, historical buildings, pretty walking paths between the shore and the edge of the forest and, on top of it all, the castle ruins of Bierseck Castle, as the crowning glory of the whole. It is a wonderful place for physical and mental relaxation, but those seeking peace and quiet should visit outside of the holidays or weekends. It is a real visitor magnet. Warning! The grottos can only be reached on foot and via steep stairs. The rest of the garden is mostly wheelchair accessible and suitable for pushchairs. There are no parking spaces directly at the Ermitage! Free entry!

The Hermitage in Arlesheim is a romantic landscape garden based on the English model. It is a place of silence, peace, contemplation, and for some even a place of strength. The meandering, playful paths make you want to discover the various nooks and crannies of the Hermitage. Here you can meet the hermit Brother Klaus or discover small cave entrances. The Hermitage also has a beautifully landscaped pond. The wooden footbridge that leads into the pond invites you to linger. The Hermitage has its charm in every season. It was opened in 1785. There is so much to say and learn about the Hermitage that it is worth taking part in one of the regular tours. Ask the Arlesheim Tourist Office or the "Friends of the Hermitage" association. Towards the end of the 18th century, the largest English garden in Switzerland was created on the Birseck castle hill. English gardens combine the natural landscape with artificial elements that are based on nature. Observation platforms, waterfalls, suspension bridges and hermits' cells were created, which were connected by winding paths. Even in ancient times, the area around the Ermitage was apparently a sacred landscape. Finds in the caves prove that this area was already inhabited in the Stone Age. "The sensitive people who live close to nature must have always noticed the high vibrations at the Ermitage, which is why it can be assumed that the hill with its caves has been the home of wise women and men for thousands of years." And even today, a secret hovers over the landscape. There are intense power spots right next to the grotto complex in the entrance area, at the rock overhang at the carousel square or on the square of the Temple Rustique. These are the power spots whose vibrations help to open the inner eyes. The Ermitage has become a true place of pilgrimage for many who know the importance of such places and appreciate their influence. Source: Pier Hänni, Magical Jura.
