Linden Avenue with 15 Rosary Chapels

As one of the most important Catholic and Orthodox Marian pilgrimage sites in the region, the pilgrimage to Schönenberg has a long tradition. The pilgrimage route to Schönenberg Church leads - coming from Ellwangen - up a steep linden avenue past 15 octagonal rosary chapels that were built in 1733 and 1734 (including the larger Marian or Lourdes Chapel and the Joseph Chapel). The pilgrimage of the displaced persons in particular attracts thousands every year. Prominent pilgrims and keynote speakers on this occasion included Chancellors Konrad Adenauer and Helmut Kohl.

The Schoenberg church, also known as the pilgrimage church "To Our Lady", is located on the 530 meter high Schönenberg near Ellwangen (Jagst) and is an important church in the region Ostwürttemberg.
