Juliana of Liège was a 13th-century Premonstratensian canoness and mystic born in Retinne, in the Prince-Bishopric of Liège. After being orphaned at five, she entered the religious life at Mont-Cornillon, where she later served as prioress. She is most famously recognized for her spiritual visions regarding the Eucharist, which inspired the establishment of the Feast of Corpus Christi. Throughout her life, she faced significant political and religious turmoil, leading her to seek refuge in several different religious communities before her death in Fosses-la-Ville.
