Research and excavation work were carried out by the Swedish Institute that revealed king Gustav VI Adolph of Sweden’s passion. It was one of the internal centres of lucumo history in Tarquinia. Today the urban part is only a deserted field. It is on an area of tuff that rises from the waters of the Vesca river on the southern side, with a high rock precipice measuring over 40 m in height. Three large ditches distance the plain that preserves the clearly visible ruins of a XIII century castle belonging to the powerful di Vico familyand a modest little church that was dedicated to the saint of Narni thus the town’s name. Evidence shows that oval shaped huts were used here up to the Bronze Age and that in the following period, that is the Iron Age, huts were also used. Garrets can be seen along with the remains of different Etruscan homes that were built of tuff that are the same as the ones of Acquarossa (Ferento) These are among the most ancient of Italic and Etruscan domestic architecture (VI cent. B.C.). One of the first consistent groups of houses is in the so-called "Borgo", joined together on both sides by narrow streets, with wells and PESTAROLE nearby; the other is in the inner part of the headland the foundations of a house with two rooms, situated one behind the other are clearly visible. In the rear room there is a low bench along the sides formed by a uniform layer of river pebbles an ingenious device against humidiy which brings to mind the pebbles present in the tomb of the Capanna (VII cent. B.C.) in Cervetri.
Remains of a wall are found on those sides that were less equipped for natural defence, particularly the ditch in front of the castle. In the valley of the PIetrisco ditch are the remains of the pillars of a bridge, one of the oldest in Italy, with tuff blocks and panel flooring. Surrounding the house are numerous hole graves, mound tombs and chamber tombs (VIII-III cent. B.C.) that exploit the plains and the rocks. Many have imitation sculptures from domestic architecture. They are particularly common in the high regions of Grotta Tufarina, Porzarago, the Grotticelle, the Vignale, Castellina Cammerata, Pontesilli and Montevangone.
