Hermitages Eremo della Trinità The Hermitage of the Trinity is located in the locality of Allumiere, in the province of Rome and is among the oldest sanctuaries of the Tolfa Mountains. It is certainly not the construction period, due to various renovations, but it is assumed in the period of the Middle Ages. Among the oldest documents to mention are the Bull of Pope Innocent IV. The Sanctuary survived until the mid-600 and was renovated in the 19th century. Currently, the restoration of the monument was completed, precisely in 2002 and is accessible to the public under the care of the religious.
