In the sixth century, Irish monk Columbanus and his disciples established over one hundred centres of scholarship and spirituality throughout a European continent that was divided after the fall of the Roman Empire. A missionary and an outsider from Ireland, he built the monasteries which became Europe's first universities, established a writing system, and risked his life when he demanded leadership from kings and even popes.This beautifully shot investigative documentary travels in Columbanus’ footsteps through Ireland, France, Austria, Switzerland and Italy, uncovering his remarkable legacy and its relevance to contemporary Europe.
