Infrared thermography and Georadar techniques applied to the “Sala delle Nicchie” (Niches Hall) of Palazzo Pitti, Florence (Italy)

Two noninvasive geophysical techniques, infrared thermography and georadar, were used in this study to investigate the internal walls of the “Sala delle Nicchie” (Niches Hall) of Pitti Palace, in Florence. The aim of this work was to verify that the original architectonic setting of this Hall was as reported in a planimetry of anonymous author dated late 1700. This document shows that the “Sala delle Nicchie” was characterized at that time by 10 niches instead of the six that are visible today. Both the infrared thermography and georadar surveys confirmed the presence and location of the niches as indicated in the planimetry. This study results prove the importance and benefit of using nondestructive techniques in sites of artistic and historical interest.
