Maria Einsiedel Pilgrimage Chapel

The first documented mention of the pilgrimage site is an indulgence certificate from 1493, issued in Rome and signed by 16 cardinals, including the later Popes Julius II and Leo X. Pilgrims receive a 100-day indulgence for donations to restore them. In 1493 the chapel and pilgrimage already existed and were apparently of a later age, as the church was dilapidated and a destination for pilgrims. The original miraculous image still in the chapel, a wooden pietà, is dated to around 1400 in terms of art history, which seems to confirm the information in the breve. According to legend, the figure was found in an elder bush and taken several times by believers to the parish church of Gernsheim, but repeatedly inexplicably returned to its original location, so that a chapel was built there for it.

Sanctuary of Maria Einsiedel

The traces of the sanctuary can probably be traced back to 829. Thereafter, the "fenced in Geroldshusa" was given to the Lorsch monastery and is probably identical to the later "Einsiedel Hof", which belongs to Gernsheim.
