Abstract
In Sicilian area, as well as elsewhere in Europe, the theatres built between the last decades of the XVIII century and the beginning of the XX century are progressively disappearing because of integrations and substitutions required by the new “modernity”, the change of use of the building itself that do not respect the original purpose. Nevertheless, beyond the updates caused by the respect of the new laws concerning the security in public spaces and a great confidence in concrete, there are still many theatres witness of this very interesting typology. This study recognizes and analyses the peculiar elements of major and minor theatre structures.
