Integrated geoscientific surveys at the Church of Santa Maria della Lizza (Alezio-Italy)

The church of Santa Maria della Lizza is one of the most important evidence of medieval archi-tecture in the Salento Peninsula (in south Italy). In order to understand the extension and layout of the crypts, integrated ground-penetrating radar (GPR) prospections and laser scanner surveys were undertaken in the church and in the surrounding areas. The analysis of the GPR measure-ments revealed many anomalies that could be ascribed to unknown structures (crypts), as well as other anomalies related to the old church. The GPR data were supported by the laser scanner da-ta making the spatial relationship between the surface and below level of the church.
