The church is a beau­ti­ful exam­ple of baroque archi­tec­ture. Today, the church serves as both a church and a Ger­man lan­guage and cul­ture school, but is prob­a­bly best known for the Heiliger Steige. The church was erect­ed in 1627/1628 on the orders of the arch­bish­op to replace an old­er chapel. In 1746 Elec­tor Clemens August von Bavar­i­an donat­ed the Heiliger Steige, or holy stair­case, which, accord­ing to leg­end has pieces of the cross the cru­ci­fied Jesus set into the stone. Small brass cross­es on the sec­ond, eleventh, and last steps mark the spots where the pieces of the cross are sup­posed to be set. Beau­ti­ful view over Bonn.
