Lake Bracciano is of volcanic origin and maximum depth of 160 meters. It has an emissary, the Arrone river that flows into the Tyrrhenian Sea near Fiumicino. Lake Bracciano, Lake also said Sabatino (Latin: Lacus Sabatinus) is a volcanic lake located in the northern province of Rome. The area of Lake Bracciano and near Lake Martignano, also of volcanic origin, characterized by a particular natural value, is included in the Regional Park of Bracciano - Martignano. Despite the attack Urbanism, in fact, the area still dealing with vegetation and forest areas of more extensive and the presence of such habitat favors the presence of numerous species of wild aquatic and not. The waters of the lake, finally, are particularly rich in fish, thanks to the fact that a regional law prevents the navigation engine, with the exception of boat that performs seasonal service between the three centers of the basin: Bracciano, Trevignano Romano and Anguillara Sabazia. On the bottom of the lake many finds attest protohistoric settlements, such as near Vicarello (Middle Bronze), to Sposetta (Middle Bronze Age and Late Bronze), or to Vigna Grande that reaches the age of iron. Around Anguillara was found a Neolithic village of submerged, lived for about 500 years from 5700 to 5200 at. C., with large rectangular houses (were dug 7) arranged orderly, presumably an area of 25,000 sq.m. and suddenly dropped to perhaps a flood. The remains that can be traced back to the economy and the diet group (grains of wheat and barley, bones of goat, sheep, dog) because in many cases are still in layers of neglect and vases. A case of cereal variety bones and in the same jar suggests a food being cooked when it unleashed the final event. Not missing the fruit: apples, plums, raspberries, strawberries and ... acorns. Still uncertain hypothesis that already produce wine. Moreover, the presence of flax suggests the cultivation for textiles, while we can not determine what serves the sleeping pill poppy from which opium is derived. The instruments include stone axes, sickles with wooden blade of flint, obsidian blades, ceramics decorated with impressions cardiali (with the edge of the shell Cardium or heart), or painted with red reasons, blacks or whites. Among the most important finds so far made known, ceramic boats, canoes hewn oak logs emptying (one shown in Rome in Prehistoric Museum of Ethnography L. Pigorini is 10.5 m long) and a stone statue depicting a woman, perhaps the "mother goddess ". The village is located in "the Marmotta", 7.5 meters deep and 350 meters from the shore current and therefore the underwater excavation, directed by Maria Antonietta Fugazzola, it is very difficult. According to a hypothesis of archaeologists, rather than a complex that, thanks to its excellent state of preservation attests characters centroitaliane events of the time, it is the appropriation of "settlers" from the eastern Mediterranean.
