"Helligkilden", a holy spring dates back to the Middle Age, where it was known under the name "Vor Frue Kilde".
This holy spring was important to the many pilgrims, who went for a pilgrimage. After the reformation the flood of pilgrims stopped and the spring became more and more dilapidated.
In 1906 the National Museum uncovered the place, where the spring originally was situated. Today the "Helligkilden" is dry, but you still can see a remnant.
