Since 1809, the San Giorgio community wanted the construction of the theater, which was decided by the city council and entrusted to the project of architect Giuseppe Locatelli. Completed in 1816 and solemnly inaugurated on January 29, 1817, the structure underwent various structural modifications until reaching its current form in 1860. In that year, the curtain was renewed, and painter Mariano Piervittori depicted the entrance of Vittorio Emanuele II in the square, the sovereign to whom the building was dedicated until 1950, when it became state property and took on the name Teatro Comunale.
The building features a brick facade adorned with a travertine plaque bearing the motto “Castigat Ridendo Mores” – one corrects manners through laughter – framed by two masks representing tragedy and comedy. In the early 1900s, the famous San Giorgio painter Sigismondo Nardi frescoed the ceiling with a grand allegory of the arts and human destiny, giving it its current splendor. After a period of abandonment and uninhabitability, a conservative restoration completed in 1992 returned the building’s remarkable beauty to the area, confirming its importance as a center for performances, concerts, and conferences.
