On the eastern slopes of the Teufelsberg, between the summit and Burrweiler at a height of 423 metres, is the Roman Catholic St. Anne's Chapel (Annakapelle), which was built in the 19th century in the Gothic Revival style and to which there are regular pilgrimages in July and August. In addition the parishes of Burrweiler and Flemlingen make their covenant procession (Gelöbnisprozession) to the chapel every year on 1 May.
