Il castello di Brolo, rilievo digitale integrato per la conservazione del Patrimonio

The castle of the historic center of Brolo (ME) is located along the Sicilian coast facing the Aeolian Islands, on top of a cliff, once bounded to the north by the sea as a natural defense. The defensive system was built to control the coastline to defend against pirate invasions and was originally formed by a lookout tower within a perimeter wall that enclosed both the buildings of the lord and residential construction. The perimeter wall has been extended with a modern triangular bastion that defends from the shots coming from the port inlet; from the end of the 16th century the castle lost its importance and was left to decay. During the Second World War it suffered bombings that particularly ruined the northern front towards the sea, restored in the 70s. The defense system documentation project is aimed at analyzing the conservation status of the monument necessary to set up a coherent restoration project; the survey was carried out using modern digital survey technologies, using a methodology aimed at integrating the morphological data obtained using laser scanner instruments and information regarding color with photographic techniques using SfM methodology. The two-dimensional drawing has allowed us to create the basis of information necessary for the preparation of diagnostic and stratigraphic analyzes, indispensable for understanding the history and the evolution of the building and its state of conservation. The urban survey was a useful tool to study how the fortification left traces in the fabric of the historic village: comparing historical data and cartography with today's drawings it was possible to define where ancient structures insisted on the territory.
