The Shrines of Gadir (Cadiz, Spain) as References for Navigation. GIS Visibility Analysis

Abstract

This work analyses the influence of the visibility factor on the configuration of the archaic landscape of the Phoenician city of Gadir (Cadiz, Southern Spain) using the three shrines mentioned by classic sources as a reference. Theoretical or cumulative viewshed analyses are the methods used to investigate the visibility relationships each of the shrines has with the sea and the surrounding territory, as well as with each other. Based on these analyses a series of theoretical interpretations regarding the function of these shrines as references for navigation in Antiquity are established.
