Saint Irmgardis, Saint Irmgard of Süchteln (1000 - † 1065 or 1082/1089, Cologne, Germany) was a medieval saint and sovereign Countess Irmgardis of Aspel (Germany) in 1013–1085. Her relics are preserved in sarcophagus in the altar of Cologne Cathedral. Also known as Saint Irmgardis of Köln, the sources show her as Reigning Countess, and after her parents died, she distributed her wealth among hospitals, churches and social institutions. She lived a simple life in solitude and went on three pilgrimages to Rome. She spent her last years in Cologne, where she supported Chapters and Convents.
