According to legend Beatus was an British monk who travelled on pilgrimage to Rome in the first century AD. In Rome he met St. Peter and became a priest. He was sent to the area North of Switzerland, crossed the dangerous alps and arrived in the area of the lake of Thun in.

St. Beatus discovered the cave around 112AD and lived there as a hermit. A terrible dragon was devastating the area. St. Beatus was able to defeat the dragon and the area turned to Christ.

Today the cave offers a lot for modern visitors: about one km of trail leads through the beautiful natural cave. A restaurant caters to the needs of its visitors. And also for the little guests there are interesting activities.
