Which Irish saint founded the monastery at Bobbio, Italy, in the 7th century?

The Irish saint who founded the monastery at Bobbio in Italy in the 7th century was Saint Columbanus.

Columbanus was born around 543 in Ireland and became a missionary monk during a period of intense monastic expansion. After leaving Ireland, he founded important communities in the Frankish kingdom, most famously Luxeuil Abbey in present-day France. His missionary work eventually brought him into Lombard Italy.

In 614, the Lombard king Agilulf granted Columbanus a ruined church and surrounding land at Bobbio, near the Trebbia River in modern Emilia-Romagna. Columbanus established a monastery there and introduced a strict Irish monastic rule. He died at Bobbio on 21 November 615, but the community continued under successors such as Saint Attala and became a significant center of learning.

Bobbio later gained fame for its library and manuscripts, as well as for its role in opposing Arian Christianity among the Lombards. It was eventually governed under the Rule of Saint Benedict, replacing Columbanus’s stricter rule. Saint Patrick and Saint Columba were also major Irish saints, but neither founded Bobbio Abbey.
