About 2800 years ago the places and the district now call Marino, were covered with wild woods and the coast degrading near the lake Albano there were a lot of springs and a broad watercourse that descended to the valley with numerous waterfalls of water crashing on the heart of the lava rock below. At that time there were many wild animals and the lake provided food to the ancient inhabitants.
Lake Albano in those days was much larger with an area three times wider than visible now, the banks of the lake touching the edges of the reservoir natural volcanic arisen by the sinking of the volcanic mountain above the empty magma chamber of the volcano.
During periods of rain, the waters of the lake and went down flooding the current area of the Appia Antica, flooding that portion of the Roman countryside until it was marshy, uninhabitable and unhealthy.
In those early times, a large area of Central Lazio had as its relevant point the Lake Albano and his namesake Monte.
Both the banks and in the vicinity of the lake were scattered villages of the ancient inhabitants and where the safe places were represented by hills protected by cliffs or steep slopes difficult or difficult to attack by armed gangs enemy.
This kind of natural fortifications made important Albalonga (old city and capital of the League) , overlooking the cliffs overlooking the nearby waters of the lake and protected by cliffs above the slopes of Monte Albano, an important mountain in those days, because on top there was established the worship of Jupiter Maximus with a large temple.
Rome at that time was not as powerful as it would later become, and the Latin League led by Alba Longa was an important reality that governed a broad alliance of villages, each held together by powerful or influential local people.
In this era there were already trade with the distant Etruscans who export their black pottery as refined goods and glossy blacks in comparison with rustic pottery produced in these places with geometric designs typical and similar to those known as 'Villanovan'.
From the Roman countryside you could go up to Albalonga through the path that goes up to the resort Marino Pantanelle.
(The Pantanelle were precisely the places where water stagnated longer and were created semi-humid and muddy but passable in the dry season as the bed of polished stone of the river, lent itself to being traveled by wagons and horses.)
For those times, this was a highway access road, and this went up to the mountain surrounded by dense forest.
The first hill climbing met was a village protected on all sides by steep rocky, this was the place where he would later rise to Marino. (The places today have been domesticated over the past 600 years and the old roughness have gradually been erased as documented in the books of local history)
Access to the village was protected by a guard outpost, built on a cliff of 10 meters and that kept both the access road to the village but also presided from access to forest Ferentano.
This outpost there came the leftovers that are made through the holes into the rock to make way for wooden poles or the skeleton for a covered structure. The floor made of living stone bears an excavation roughly rectangular (approximately 60 x 40 cm. In the center of the house and which should correspond to the cockpit where you could keep a fire going.
Below this outpost, on the one hand and the other the banks of the river stood the rocky walls or eroded by water or dug by man, were opened in natural caves that provided shelter for the night if necessary. Later at about 2000m was reached at Bosco Ferentano, a sacred place because it kept small temples are dedicated to the worship of the gods naturally present in the place or the deification of the river, streams, springs, the spirits of the forest, etc..
Walking through the forest rose to the shores of the lake where you could go to get to Albalonga or climb Mount Albano to make sacrifices and thanks to Jupiter Maximus.
Over time, the village of Marino came under the influence of ROMANS-that become part of the Latin League-helped to strengthen the defenses and fortifications probably replaced by poles made then with stone fortifications, to effectively protect the village but especially the armed guard by sudden attacks, making this place a fortress (for the time) with purely defensive purpose. Moreover for this site was easy to make reports with flames or fire visible from the side of Alba Longa, as in air line nor the woods nor other natural obstacles stood in the way of sight, then as now.
In this phase, the village is enhanced by an epithet Roman fort or fortress Castrum and MOENIUM provided with walls, this is the name for the Latin spoken by the educated nobility or the nobles of the time, while the language of VULGUS, ordinary people must have bribed the original name into MO-R-I-NIUM and then later MARINO.
Today, of the CASTRUM remained only the noble, the square known as the CASTELLETTO, which still gives a glimpse of the gables of stone 's access to the temples and behind the walls of the houses, the ancient columns or the ancient town once devoted cults of the gods or the home of Decumano or some ancient family ROMAN, you also recognize hovering, the square and the traces of ancient portals.
