Torri costiere della Calabria Citra. Il caso della Torre-Isola Talao a Scalea (CS)

The proposed contribution, within the framework of a survey of the coastal defence system of northern Tyrrhenian Calabria – currently concentrated in the border territory between Calabria and Basilicata – proposes as a case study the digital survey of Torre Talao in Scalea (CS). The tower, built following the order of the viceroy Don Pedro Afán de Ribera in 1563, is located on a rock, previously surrounded by the sea, called insula parva, already inhabited in prehistoric times and now incorporated following the advancement of the coastline. The structure has a quadrangular plan and is developed on three levels above ground. The tower has a truncated pyramid shape, with a side of approximately 14.5 m at the base and 10 m at the top. The survey, carried out through digital photogrammetry, involved the integration of shots acquired by drone and images from terrestrial photogrammetry. On the basis of the survey, a digital model was produced.
