Ida of Toggenburg was a Swiss nun and hermit who lived from approximately 1140 until 1226. Born in Illerkirchberg, she is celebrated in local folklore and religious tradition for her piety. According to legend, she survived a fall from a castle after being falsely accused of infidelity by her husband, a count. Following this, she lived a life of devotion, eventually residing as a hermit near the Fischingen monastery, where she spent her final years.
