The article mentions that a bone fragment of St. Brigid's relics is believed to be in the Church of St. John the Baptist in Lumiar, Portugal. This relic was taken there in the 13th century by Irish knights to protect it from destruction during the Reformation. The relic's presence in Portugal is part of the broader history of St. Brigid's remains, which were moved from Ireland to protect them from Viking attacks and later hidden to prevent desecration. The return of her relics to Kildare, Ireland, marks a significant event, as her relics have been away from her homeland for nearly 1,000 years.
