Abstract The study aims to characterize the seismic behaviour of the Doric Column, last remaining of the Hera Lacinia Temple, located on the promontory of Capo Colonna near Crotone (Calabria, Southern Italy). Recordings of ambient vibration has been acquired both at the base and on the top of the column, simultaneously, in order to detect the predominant frequencies of the element. In addition, a high-resolution 3D model of the column has been reconstructed through laser scanning to support the analysis of the current state of the heritage element. The fundamental frequencies of the column and those associated to the site have been compared to verify potential resonance phenomena at the occurrence of an earthquake. In addition, a significant inclination of the column was detected by analysing the 3D model.
