Saint Irmgardis was an eleventh-century German countess and abbess who lived in the regions of Rees and Cologne. Born around 1000, she held the title of Countess of Aspel. Following the death of her parents, she chose to use her inherited wealth to benefit various social and religious institutions, including hospitals and churches. She eventually embraced a life of solitude as a hermit and made three separate pilgrimages to Rome before spending her final years in Cologne.
