It is a solid and harmonious brick building dating back to the late nineteenth century, almost as a warning of the new times, it replaced the ancient Palazzo Defensorale, seat of the Municipality. The Palazzo and the Collegiata had dominated the main square for centuries, symbolically reproducing the scheme of the two Supreme Powers of the Evo that had generated them both, one emblem of the temporal power and the other of the spiritual.
The Municipality approved the construction of the new Town Hall on 10 May 1863, but in fact, following the expropriation of ecclesiastical assets, the Municipality of San Ginesio since 1864 he had the Convent of San Francesco available for his seat and never used the new building built in the Piazza that, at first tacitly, it was then destined to house the theater.
The works of the building were entrusted to Eng. Girolamo Filippucci who decided to move the building back in order to leave the facades uncovered on all sides and enlarge the overall area of the square. On 19 May 1874 the city council decided "that a theater be built on the second floor of the municipal factory located in the square ...". This task was entrusted to Eng. Dionisio Frapiccini. The decoration and furnishings of the Theater were contracted out to the painter-decorator Pietro Giovanetti. On the lower floor the "Aristide Morichelli" City Club was founded. The hall of that club will be decorated in the early twentieth century by the painter Guglielmo Ciarlantini.
On 20 February 1877 was approved on Organic regulation of the Society of Palchettisti of the Sanginesio Theater and it was decided to give the theater the name of Teatro Comunale. The title of Giacomo Leopardi will appear in official documents only around 1903.
The theater was inaugurated on 18 August 1877 with the band opera Addina or The wedding in Pasquella, specially composed by the Ginesino master Vincenzo Bruti, on the comic idyll of Alfonso Leopardi.
