Romuald was the founder of the Camaldolese order and a major figure in the eleventh-century "Renaissance of eremitical asceticism". Romuald spent about 30 years traversing Italy, founding and reforming monasteries and hermitages.

The Camaldolese Hermits of Mount Corona, commonly called Camaldolese, is a monastic order of Pontifical Right for men founded by Saint Romuald. Its name is derived from the Holy Hermitage of Camaldoli, high in the mountains of central Italy, near the city of Arezzo. Its members add the nominal letters E.C.M.C. after their names to indicate their membership in the congregation. Apart from the Roman Catholic monasteries, in recent times ecumenical Christian hermitages with a Camaldolese spirituality have arisen as well.
