Il digitale e la rappresentazione: la seconda linea e il castello dimenticato di Fiumedinisi

Abstract

[EN] The Belvedere Castle of Fiumedinisi (ME) belongs to that historical heritage of Sicily characterized by abandoned and forgotten military architecture. Along the Ionian coast the defensive problem has been particularly felt over time, due to the proximity of the Turkish coast, the Middle East and the African one. The first defensive line was the coastal one, defined by principals placed on the sea in a strategic position for direct control of the coast. They were part of this group: the Maniace castle of Syracuse, that of Augusta, of Brucoli, of Catania, of Acicastello, the Tocco of Acireale, Schisò in the territory of Giardini, Capo Sant'Alessio, the Saracen Tower of Roccalumera, Capo Grosso in Ali , San Salvatore in Messina. Along the eastern side of the Peloritani mountains from Calatabiano to Messina, the island's defensive strategy also included a second line of fortifications, which controlled a more distant horizon from their position. These include the castle of Calatabiano, Taormina, Castelmola, Forza d’Agrò, Savoca, Fiumedinisi, Scaletta Zanclea, Santo Stefano di Briga, Matagrifone. Among them, the Belvedere castle of Fiumedinisi, at a critical distance from the village, so as to be in a state of neglect, among those listed is that which is in the worst conditions. In stark contrast to the dignity and history of the site and territory of Fiumedinisi, dating back to the Greek period. In this work we propose the survey of the castle with digital, photogrammetric technologies, Structure From Motion (SFM) and dense matching, to arrive at a 3D documentation and graphic drawings, considering that to date there are no significant scientific surveys and representations of this abandoned fortress.
