The restoration of the basilica of Santa Caterina D'Alessandria (Galatina-Italy): Ground-penetrating radar and laser scanner surveys

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 Saint 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 non-destructive techniques (NDT) was undertaken inside and on the façade of the Basilica in order to investigate the oldest structure of the church and to help in restoration work. The NDT analysis showed a series of anomalies that could be related to old plant of the basilica and helped the restoration work.
