Here the presence of a timber structure was considered very likely because the arrangement of this area together with the Auditorium on the ground floor can be dated back to 1950s; in that period the pre-existing Royal Chapel, that developed with its height along two levels, was completely transformed with the creation of an intermediate floor in order to ensure the continuity of the expositive path [7]. Then this supposition was confirmed by the thermography as shown in Fig. 4c.

Fig. 5 reports the results of the thermographic survey related to the vaults covering the rooms 9, 10 (both painted) and 11. In particular, the thermographic image related to room 11 confirmed that it is not structural, as already suggested by the presence of a thin wall in common with the adjacent room 47.
