I sincerly express my happiness for your interest in the Nuragic culture..unfortunately most of what has been described is either completely under misconception or just simply wrong information..
Nuraghes are not just towers but spiral reels with a precise location towards the southeast,it is also stabled on a natural magnetic field location.. Etc many pseudo archeological concepts were divulged as if they were towers for defense, silos for grain and other silly ideas made by people who wanted to appear as pioneer of the unknown..the Nuragic culture is indeed a challenge because it requires a very deep and wide knowledge of physics, mathematics, electro magnetic and astronomy knowledge besides serious palaeontological study..Archeology is not an exact science for so to study Nuragic culture one needs a large participation of many sciences..until this is not properly done (which will be an embarrassment for many previous researchers) no concepts can be fulfilled with a serious back up..the worst of all is the continuous hidding of evidence of such a highly developed culture for the time of it's surrounding neighborhood... No fairy tale..serious science research in the true sense of the word...
