The joyous feast of Corpus Christi honors the presence of body and blood of Jesus Christ in the Eucharist. It takes place on the Thursday after Trinity Sunday.
June 4, 2015 was a public holiday in Graz, and many spectators lined up near the Dom, along the Herrengasse, and in the Hauptplatz to view the procession of the Blessed Sacrament (contained in a golden monstrance).
