I don't know how to answer you, I can only tell you that the archaeological site was abandoned and that they then carried out restoration and conservation works now it is open to the public and can be visited, it is located several kilometers from my house, I don't go often, near home mine recently restored a dilapidated stilo castle on the stilaro valley that dominated the valley, the area is impervious and rocky to transport the materials and machinery necessary for the conservative restoration, they had to build a monororaia, a sort of railway with wagons and a cableway , I must have some photos, you can access the site on foot. very picturesque and evocative as a place. pity that our administrators are superficial in maintaining the territory, tourism could be an excellent economic resource.
