Abbey of San Guglielmo al Goleto
The monastery was founded by Saint William of Vercelli in the year 1114. It was started as a female cloister, with a small attached monastery for the spiritual guidance and economic assistance of the nuns.
The period 1135-1515 was known as the "Age of the Nuns." The cloister became wealthy from 1135 to 1348 until the black death struck and the cloister began to decline. On January 24, 1506, Pope Julius II declared that, upon the death of the last abbess, the cloister would be closed, which occurred in 1515.
The age of the nuns was followed by the "epoch of the monks" from 1515 to 1807. When the cloister closed, the monastery merged with that on Montevergine and began to grow. Pope Sixtus V, who was also superior of the Franciscan Convent of S. Angelo dei Lombardi, accelerated this growth. The monastery reached its peak between the mid-seventeenth century and the mid-eighteenth century.
