On the west bank of the Marangone ditch, exactly on the border between the city of Civitavecchia and Allumiere is a unique almost circular structure  prehistoric. The place is known topologically as Macchia of Codata (locally Codata of Macine). The structure is built of dry stone, the stone is a sedimentary rock consisting of a whitish color to the high content of limestone, probably originated from a clay of the Miocene. The shape of the structure height is slightly truncated cone, from a visual analysis that consists of at least three concentric circles (outer diameter of approximately 13m) interrupted by what looks like a trapezoid entrance. In the innermost circle there is a paved oval pit with a stone about the size of 2 mx 1m. The structure does not seem to have some orientation astral. The prehistoric site was discovered by A. Maffei Centum Cellae association of Civitavecchia in 1961 after deforestation and was investigated in 1968 by prof.Renatao Peroni who we interviewed told us that he did not find any findings, but a few tens of meters discovered a tomb in a rectangular well, paved with stones dry, dating from the fourth sec.B.C. The prehistoric site is commonly known as "Labyrinth of Codata". We know that the Etruscan tombs ellipticals of Vetulonia resumed an aspect typical of the Neolithic-neolithic transition period (A. Zifferero, Mefra vol.118, 2006) and in particular the so-called "Tomb of the Duce" is very similar to the Labyrinth of Codata. Other similar structures are the tombs of Murgia Timone investigated by U. Rellini and D. Ridola (late Neolithic) and the circular tombs (early Iron Age) Elba island. At about 500m from the labyrinth, in the “Le Macine” place, is a village in the Middle Bronze Age (1700-1400 B.C.) investigated several times by A. Maffei (1961 and 1971). During an excursion to about 100m from the archaeological site we found the entrance to a cave (now collapsed) and two tombs, one in a rectangular well (Peroni?) and the other equipped with an dromos passage (entrance hall), then close the  Marangone ditch we found a unique pyramid-shaped structure partially derived from a sedimentary rock (Macigno type), maybe he should be a milestone indicating the presence of the sacred area. We know that the labyrinthine structures of circular or spiral are connected to the ancient cult of Dea Mater, a monotheistic religion that starts from the Upper Palaeolithic (Venus of Willendorf 25000 B.C.), which develops fully in the whole of the Mediterranean and East-Europe starting from the Bronze Age (2500 B.C.). The labyrinth is a spiral so the navel of the Dea Mater, which was devoted to prehistoric man. There are mazes latest in Sweden (Trojaborg 1200 B.C.) during the Middle Ages in which the girl was placed in the center and waited for the guy walking the labyrinth came to her and kissed to seal a marriage proposal, a clear recollection of a cult linked to fertility. We know with certainty that the Tolfa mountains are linked to the cult of the Dea Mater least the Neolithic period (7800 B.C.) through the discovery of the "Venus of Marmotta" in Lake Bracciano (F. Delpino, BPI, vol.91-92, 2001) . We can conclude that the "Labyrinth of Codata" was definitely related to the nearby village of Macine and more than a tomb of a chief was to be a real prehistoric sacred altar. In fact, the central hole was intended for some kind of rite or chthonic (the deceased was placed in the hole through a ritual before being buried in a tomb) and social transition (the child could enter the hole and getting up after a ritual as a man-hunter or warrior). Analyzing especially the stone circle of Murgia Timone and making a comparison with the rough stone is made with the sacred altar of Codata we can definitely date the property at least to the Middle Bronze Age (1700 B.C.). Uncertainties aside from the "labyrinth of Codata" is unique in the Lazio region and perhaps in Italy, as both have passed into oblivion there we can explain, but certainly should be enhanced and a cleaning, done by volunteers if the money is there, under the supervision of archaeological supervision is urgently needed, before it disappears under the plow.
