This work expands the study of the conservation of organic specimens of historical and artistic interest,assessing both biological and physical-chemical conservation requirements, in order to arrive at thetangible solution, set out herein. The results of the experiment carried out on the prototype demonstratedthe performance in terms of gas tightness achieved by the system, as well as the ability to maintain stablestorage parameters for a very long period of time. During the course of the study, the chemical compoundsemitted by the materials used in construction were taken into consideration, and the effect of the climaticvariations present in museum exhibition areas, archives or churches on the physical properties wasmonitored. This study saw the development of two innovative patented technologies (IT-1398645 andIT-1425729) applied to the construction of two cases, designed to conserve and display the mummiesof Rosalia Lombardo (1918–1920 AD) in Palermo, Italy and Princess Anna of Bavaria (1319 AD) in Kastl,Germany.
