GPR and ERT surveys at the Castle of Melfi (Potenza, Italy)

This paper presents some of the results of the GPR and ERT surveys conducted at the Castle of Melfi in order to document the presence of ancient buried structures. The fortress is made up of several buildings modified and added over time: the original core of the structure dates back to the Norman period and was probably built on a previous Byzantine castrum between the end of the 11th and the beginning of the 12th century; it was enlarged in the Frederick era and underwent further modifications in Angevin and Aragonese period. Integrated GPR and ERT investigations were conducted inside two courtyards of the westernmost part of the fortress, the Cortile degli Armigeri and the Cortile del Mortorio, and two isolated ERT profiles were also measured on the north-eastern sector of the external walls and in the underlying stretch of the moat.
