The most famous of the Augustinian hermitages is unquestionably Lecceto Hermitage, still inhabited today by a community of Augustinian nuns. Located about eight kilometers outside Siena, it is easily reached by going out the San Marco gate and continuing along the provincial road from Siena to Sovicille. A desired destination in the past for anyone seeking to live the hermitic life, this fortress-hermitage is immersed in a silent mystical atmosphere on the edge of thick woodlands. Of the five Augustinian hermitages in Sienese territory, Lecceto, originally called Foltignano, is the only one for which we do not know the date or the name of the founder. A legend claims that Augustine wrote his Rule for this very community at Lecceto on his way home from Milan. Even though historical documents indicate the improbability of this legend, the hermitage has always enjoyed an undisputed spiritual importance. Saint Catherine of Siena  wrote many letters and made numerous visits to the Augustinian friars, especially to Father William Flete, who had the greatest influence on the spirituality of the saint.
