San Cono (Sicilian: Santu Conu) is a small village and comune in the Metropolitan City of Catania on the island of Sicily, southern Italy.

Ottavio Trigona (although busy with the administration of Piazza Armerina, the neighbouring town) never neglected the interests of the feud of San Cono.

It is said that one day the Marquis Trigona received a visit from a Friar of Naso who belonged to the Order of St.

But after a long period of time the Marquis, having no longer been visited by the monk (and beginning to doubt his good faith), decided to go personally to Naso to ask for information; yet no one was able to tell him anything about the Friar.

Ottavio Trigona asked and obtained a "licentia populandi"(This was a concession or permit by the Kingdom of Sicily, for barons or feudal lords to allow them the privilege of populating a feud.

Today the Trigona palace is found to be divided into various owners, who over the years have made profound changes without taking into account its historical and cultural value.
