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/

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.

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!
