Ninnoc was a 5th-century abbess born in Wales who later established a religious community in Brittany. According to her hagiography, she chose a life of devotion over marriage after being inspired by the preaching of Germanus. Upon arriving in Brittany, she received land from King Gueric to found a double monastery for both men and women. This settlement, which eventually became known as Lannennoc, served as a center for spiritual life and practical instruction for the local population.
Life and work

As an abbess, Ninnoc provided sanctuary to women seeking refuge and supported the local community by teaching new agricultural methods and the importance of planting trees. Her monastery, located near Ploemeur, functioned as a significant religious site for many decades. Although her life is documented in a 12th-century text, she is remembered for her role as a protector of the poor and vulnerable.
Veneration

The saint is commemorated on 4 June, which is traditionally considered the date of her death in 467. In Brittany, she is honored as a virgin and abbess. Her iconography sometimes includes a stag at her feet, a symbol potentially linked to a story where a hunted animal sought shelter within her church, leading to further royal support for her monastery.
