This bunker is one of several in Bettlach. Like the others, it can be viewed inside. Since it's pitch black, a flashlight is recommended. There's also a bunker trail that takes you to two more bunkers in the forest.

In 1913 and 1914, following the ideas of Johann Knauth, architect of Strasbourg Cathedral and curator of the M.H., the nave, the side chapel of the Sacré-Coeur, the Saint-Joseph Chapel in the basement, and the sacristy were rebuilt in the Gothic style by the architect Alexandre Louvat from Mulhouse. The old Gothic nave, remodeled in the 18th century, was decorated with murals dating from 1491. To the south of the choir was a small chapel dating from the 14th and 15th centuries, with cross-ribbed vaults on consoles. To the north were the remains of the old priory cloister. On the site of the present Sacred Heart Chapel was the 18th-century Mount of Olives, the rood screen of which was removed in 1861.
