Ground penetrating Radar survey at the Basilica of Santa Caterina D'Alessandria (Galatina Italy)

The basilica of Santa Caterina D'Alessandria was built between 1369 and 1391, by order of Raimondello Orsini del Balzo. These, on one of his many journeys, returning from the Crusades, went as far as the summit of Mount Sinai to pay homage to the body of S aint Catherine. The building, on Raimondello's death in 1405, will be completed by his wife, Princess Maria d'Enghien, and then by his son, Giovanni Antonio Orsini Del Balzo. A study, using ground penetrating radar tecnique ( GPR ) was undertaken inside the Basilica in order to investigate the oldest structure of the church. The GPR analysis showed a series of anomalies that could be related to the old plant of the basilica.
