Saint Erentrude, niece of Saint Rupert of Salzburg, was the first abbess of Nonnberg Abbey in Austria. Born in the late 7th century, she led the community in service to the poor and sick, balancing prayerful seclusion with active charity. She died on June 30, 718, and is venerated for her healing intercessions.
Saint Erentrude, also known by the variants Ehrentrudis, Erentrudis, or Ermentrude, was a noblewoman of Franconian-Merovingian lineage who became deeply involved in the Christian mission in the early 8th century. Likely born in the late 600s, she was the niece (or possibly sister) of Saint Rupert of Salzburg. After accompanying Bishop Rupert from Worms to the area that would become Salzburg, she became a founding figure in the region’s spiritual life. Around the year 700, Rupert established the Benedictine women's convent on Nonnberg Hill, placing Erentrude as its first abbess. There, she and her fellow nuns devoted themselves to communal prayer, manual labor, and caring for the poor, the sick, and orphaned children . Erentrude’s abbacy was marked by a compassionate balance between cloistered devotion and active ministry—she and her community routinely ministered to those in need beyond their walls . Contemporary accounts note her special care for children and the ill, confirming her deep love and pastoral concern .
In early 718, upon entering her years of declining health, Erentrude received a vision of her uncle Rupert instructing her to come to him in death. Following Rupert’s passing in March of that year, she died on June 30, 718. She was interred in a simple, unadorned grave among the rocks beneath the convent .Over time, her relics became a focus of veneration. In the 11th century, Emperor Henry II rebuilt Nonnberg Abbey as a token of gratitude for being cured of leprosy through her intercession. Her remains were ceremoniously moved into a silver reliquary beneath the altar on September 4, 1624—a date once commemorated liturgically until Vatican II .Numerous miracles followed her death, including reports of healing lepers, curing the blind, and even the story of an abbess who stole a relic and was struck blind until repentance . In 2006, her image was featured on a commemorative Austrian coin honoring Nonnberg Abbey, and later appeared on a postage stamp Saint Erentrude is honored in both the Roman Catholic and Eastern Orthodox Churches, her feast observed on June 30. She remains a secondary patroness of Salzburg, and her crypt endures as a place of pilgrimage and devotion .
