A beautiful chapel along the way, with an interesting information panel about the escape of a French officer during World War II.

Mörsberg Castle, sometimes called the "Alsatian Pierrefonds," contains impressive remains of the defensive structures surrounding its keep: the flanking tower, which defended the former lodge with several window openings, and the enormous vaulted cellar, more than 50 meters long.

At this point / I would like to quickly / say something about the source And specifically to quote the incomparable humorist Heinz Erhardt (1909 - 1979), who was known to a wide audience for his wit and "Another poem", with a short four-line line: "There is certainly a lot of beauty in the element, the wet. Because you can drink the water. But you can also - not." (H.Erhardt)

The whitewashed chapel, which is simply designed on the outside, has no turret, but there is a small niche above the door on the entrance side - there is a seated Virgin Mary with the baby Jesus on her lap - and above that on the gable wall is a cross. The interior is also simple but dignified: in the apse there is a large statue of the Virgin Mary, on the side wall on the right a crucifix and on the left a framed picture of a saint.

The Largue has its source in Oberlarg at an altitude of 500 m, near the Swiss border, and flows into the Ill at Illfurth after traveling 46 km. In the 19th century, it provided energy for 53 mills spread across 34 villages.

Enormous cellar whose entrance is 4 m high. It is currently filled. It is one of the rare caves known in Alsace.
