The Mother Church of San Lorenzo of Aidone, in Sicily, is perhaps the most ancient church of the village and dates back to the XI century. Rebuilt after the massive damage suffered in the earthquake of 1693, of the original Norman system remain the lateral buttresses and the portal. With reconstruction were added the side chapels and the bell tower, never completed. Traces of the ancient structure are visible in large parietal ashlars discovered in the sacristy, in correspondence from the apsidal area. The facade was rebuilt using the ancient material: were recovered the two grooves on one side of the door, which represent the measures of the palm and of the barrel, but not the ancient inscription whose fragments are scattered throughout the facade. Interesting the ridges of the cantonal impressive finished with characteristic shapes in a spiral.
Inside are preserved furnishings, sacred furnishings, antique vestments, statues and paintings in the part coming from the convent of Santa Caterina: between these objects, the reliquary of silver in the shape of an arm, containing the relics of San Lorenzo, probably brought from Rome from Marcantonio V husband of Isabella Gioienis, the latter of the family of Gioienis that had introduced the cult of the Saint for an alleged miracle. There are two versions on why San Lorenzo, at the behest of the family Gioienis, was declared patron saint of the country instead of San Leone: according to one of them was Giantommaso Gioienis in 1531 to introduce the veneration for the holy martyr in thanksgiving for the salvation of his son Lorenzo from the plague. According to another version was instead Isabella Gioienis, in the second half of the Seventeenth Century: married to Marco Antonio Colonna, which had brought a dowry in the feud of Aidone, would not have been able to have children and promise to vote to the saint of it becoming the patron saint of the country if he had given birth to a son; the grace would have been granted and Isabella gave birth to his son Lorenzo and he kept his promise. The 1810 instead dates back to the birth of the Accademia di San Lorenzo, who worked for at least a century.
