It is the oldest and most significant ornament of this church and the focal point of a regional pilgrimage today.
The design of the crucifix was based on the forked cross at St. Maria im Kapitol in Cologne.
In the interior are four relics, the origin of which is either totally unknown or can only be loosely estimated: a bone wrapped with silk which cannot therefore be identified, two human ribs and a light brown stone, probably from the Holy Land (the hill of Golgotha?)
The post of the cross was originally painted green, this alluded to the Biblical tree of life symbolism.
During the Neo-Gothic restoration in 1860 the Bocholt Cross, as part of a mercy seat was integrated into the high altar.
