The former convent of the Friars Minor Observant is a recently restored, extremely impressive structure with a view of the village of Genoni and toward the Giara Plateau. It was built and dedicated in 1638 to Saint Sebastian. The adjacent church, preserved over time and restored, is now dedicated to Our Lady of the Sacred Heart.
The decision to found the Convent dates back to December 12, 1609, while the assent from the competent Ecclesiastical Authority was given on July 20, 1638.
The deed of incorporation is dated October 14, 1638.
The inhabitants of Genoni participated in its construction free of charge, with one working day each, as established by the chapters of agreement between the Friars Minor of Sardinia and the Community of Genoni.
From the end of the 18th to the beginning of the 19th century, however, the Convent of St. Sebastian went into decline, and in 1862 the Convents of the Province of St. Saturnino (of which Genoni was also a part) were suppressed by the Italian Government.
