THE GIUSSO CASTLE AND THE FOUNDATION AREA OF SICIGNANO DEGLI ALBURNI (SA): SURVEY AND 3D MODELING FOR SOCIAL AND TERRITORIAL VALORIZATION STRATEGIES

This paper, part of a larger research program of the Faculty of Engineering in the International Telematic University UNINETTUNO, aims to document, through the survey as main instrument, a path of knowledge about the fortified architecture known as Castello Giusso and its surrounding area, with the ruins of the church of San Matteo Apostolo ed Evangelista. The site is the primitive nucleus of the town, developed in the Middle Ages under the castle and the patronal church as long as existed. The first step has been the survey: the Giusso castle is a vast and articulated architectural complex. For the morphological conditions, advanced technologies were used and therefore the decision to operate with the laser scanning to acquire the measurement of the surfaces. A laser scanner able to acquire reliable data even at various distances was used, creating computer scans of considerable weight. The processing of data (still in progress) has the main aim to create different 3D models: the survey model is essential to obtain a thorough knowledge of the architectural heritage; the stratigraphic model is useful to define the development of the castle in the different age; the virtual reconstruction of the site at the date of the XIX century offers us the vision of the original morphology with the Church of San Matteo Apostolo ed Evangelista. The castle and the archaeological area around it is an important resource to a sustainable development of the whole town.
