The wonderful view of the entire Pontine Area and its Islands, which can be enjoyed from Monte Sant’Angelo alone, deserves this excursion.
The promontory of Monte Sant’Angelo (227 meters above sea level) constitutes an offshoot of the Ausoni Mountains which at this point come to overlook the Tyrrhenian Sea, dividing the Pontine area into two parts: to the east the fertile plain of Fondi and to the west the Agro Pontino proper (the former marshes, also today one of the most fertile areas in Italy). Since 2000 this place has been part of an Archaeological-Landscape reserve.
This mountain was called Monte Nettunio and this until the Middle Ages, when the Monastery of Sant’Angelo was built there; until the underlying Pisco Montano promontory was cut. For the first three centuries of its construction. The Ancient Appian Way climbed up this mountain and then descended on the opposite side, before its route could be moved to sea level. During the time when the Appian Way passed, a settlement and a place of worship arose here, as evidenced by the numerous structures currently found in the area of the temple of Jupiter Anxur. Among other things, today it is no longer so sure that the divinity to whom the Temple was dedicated was precisely the Iuppiter Anxurus (child Jupiter); in fact, on the basis of inscriptions found, according to many, the sanctuary was perhaps dedicated to Venus, but further research in progress could reserve other surprises in this regard.
It was at the time of Silla (2nd century BC) that the area (where a famous oracle was also located) took on features of Monumentality.
