Survey and 3D modelling of Castel del Monte

Castel del Monte, symbol and emblem of the buildings Federico II architecture, seems has been realized for wish of the same Federico II on 1240. In 1876 the castle has been acquired by the Italian State and numerous interventions of restauration have been take. From 1996 Castel del Monte has been inserted by the UNESCO in the worldwide patrimony of the humanity for his oneness and it’s currently the monument more visited of Puglia. Numerous and rather fanciful hypotheses have been argued around original destination; such as many have been the interpretations around the octagonal matrix of the castle and the number eight, recognizing in these elements magic, ancestral, esoteric, astronomic references; by according to some researchers, the castle would have even hosted the Saint Graal. The originality of the site has induced a surveying more deepened through laser scanner technique, for the complexity of the structure, it was to plan a simulation of surveying steps. The above mentioned phases have allowed one more expeditious activity of survey; particularly the laser scanners survey have allowed a 3D model that could allow to verify different hypotheses or to formulate new one.
