Located just outside the city of Rieti, where the chapel of San Fabiano once stood, here the Saint found hospitality in an adjacent house while waiting for surgery.
According to tradition, San Fabiano witnessed two important events linked to the presence of Saint Francis in this place: the miracle of grapes and the composition of the Canticle of the Creatures. Two exceptional events, the second above all, that turned this lonely monastery in one of the most sacred places of Franciscanism.
The sanctuary, as it was at the time of Saint Francis, consisting in a church, a rectory and a domus house, remained such until the early years of the fourteenth century, when the Romiti friars began the transformation by demolishing the interior walls of the rectory and erecting a second larger church, that of Saint Fabian. Changes continued to take place also when the monastery passed on to the hands of Clareni order, who built a small convent with a cloister.
