Since 1926, the monastery church has borne the papal title of honor of a Basilica minor. Originally built in the late Gothic style, the interior was redesigned several times and furnished and painted in the Neo-Baroque style between 1900 and 1934. The mighty high altar at the end of the choir, a gift from the French King Louis XIV, was consecrated in 1680.

The Mariastein monastery is considered the second most important pilgrimage site in Switzerland after Einsiedeln. Its origins go back to a legend in which a little boy fell over a high rock face and was then found unharmed by his mother. After he told his father that he had been caught by a woman, the father was sure that it was the Virgin Mary. He had a chapel built in a cave in her honor. The monastery complex can be visited daily, but services are held regularly. More information can be found here: https://www.kloster-mariastein.ch/informationen/agenda/

Great gorge just outside Basel with a lovely fireplace. In midsummer, when the temperatures in the city are hot, this detour into the cool gorge is particularly worthwhile. Very interesting for children, as it is only a 10-minute walk from the car park.

The Mariastein monastery is, alongside the Einsiedeln monastery, the second most visited pilgrimage site in Switzerland. Thousands of believers and pilgrims from all over the world make a pilgrimage to Mariastein every year to ask Mary for help or to receive her blessing. Of course, the impressive monastery complex and the surrounding lands attract numerous tourists and hikers every year, who bring home a wealth of memories with a suitcase or backpack, but also a full photo or cell phone memory card. A detour to the gift chapel hidden in a rock grotto and the magnificent basilica is particularly recommended. If you visit Mariastein, you should also, if possible, pay a visit to the nearby castle ruins of Château Landskron in Alsace, just a few minutes' walk away.

I could no longer see any ruins on this overgrown rock. The narrow path, which seems to be taken from a fairy tale book, leads to Biedertal Castle, but is always worth a visit. Once you arrive at the castle grounds, it is not immediately clear where the path continues. If you want to visit the castle rock cave, the narrow path leads through the buildings and down into the forest. The cave itself exudes a very special atmosphere.

The rocks of the Grotte des Nains form an impressive gorge, approximately 25 meters high. According to legend, the little women of the earth lived here with the Erdmanala (little men of the earth). The gorge gives access to the Plateau des Nains and a beautiful view of the Ill valley.
