Санти-Куаттро-Коронати
The abbey soon increased its power and prestige thanks to numerous donations. In 1138 its possession extended from Rome (the basilica of Santi Quattro Coronati) to Perugia, Spoleto and Camerino. In the following centuries it had 97 monasteries, 41 churches and 7 hospitals. In the late 15th century the abbey passed to the Olivetan Benedictines.
