To around four kilometers from Sant'lppolito the castle of Sorbolongo rises. The popular legend makes to go up again the name of the suburb to a particularly tall sorbo that was found on the hill. This is represented in the coat of arms in which the tree together sinks its radixes under the boundaries of the castle to a dove with branch of staid ulivo (symbol of peace) on the summit of the hill and three stars in sky.
The birth and the development strengthened of the suburb are direct and scanned by the sequence of the historical stories. The recovery of trusts of prehistoric (in the place S. Martin of the Plan) sheds, of funeral furnishings, of rests of constructions and sundry archaeological material testify that the territory has been inhabited since the most ancient times and it is probable that also the place of the actual Sorbolongo has been center of an installation primitive embryo of the following strengthened castle. You can reasonably hypothesize the origin of Sorbolongo with the sunset of the empire Romano, when the repeated barbaric raids, that followed him from the IV to the VIII century, forced the populations to run away from the valleys to shelter him in elevated places, better arguable and above all places out of the usual routs of movement of the army. The due origin to the dispersion of the inhabitants of the can be likely "municipium" of Forum Sempronii (actual Fossombrone) or to the survivors of the ancient Suasa, Roman town hall in the valley of the Cesano zapped by the hordes of Alarico in the V century. It is certain that the area subsequently became dominion of the Longobardis and then of the Franchis, from which you/he/she was given, with the other earths of the Esarcato, to the Roman Church that governed you through vicars up to the drive of Italy. In the period of the struggles town party of the territory repeatedly fell under the dominion of the city of Fano that, from free and Common powerful person, assembled his/her expansionistic ambitions on the near Fossombrone. With every probability the same fate also touched to Sorbolongo, whose parish, in 1290, you/he/she is nominated among he/she asked her some Diocese of solvent Fano the tithe to the Pope. In the Bead sent in 1224 to Fano to Pope Onorio III to the Bishop Monaldo the "castrum Sorbilungi omnibus cum suis pertinentiis" you/he/she is nominated among the belonging places to the Diocese of Fossombrone. During the centuries the territory of Sorbolongo, being situated to the limits of the Contado fanese, you/he/she was divided between the dioceses of Fossombrone and Fano. Particularly to the first one the parish of S always belonged. Maurice, situated not too far from the suburb; the historical nucleus was hourly instead subject to the one hour to the other Diocese. The affiliation day Sorbolongo to Fano is confirmed by the Description of the Brand Anconetana however, compiled by the Cardinal Egidio Albornoz in 1356, in which the castle appears inclusive among the possessions fanesi governed by the Malatestas vicars of the S. Center. After the end of the dominion malatestiano, Sorbolongo kept on making party of the Contado of Fano under whose cognisance remained subsequently also. In the 1656 first pontifical census and in that following of 1701, compiled in reference to the areas ecclesiastical, Sorbolongo appears in the belonging territory to the Dukedom of Urbino and subject to the Diocese of Fossombrone. Administratively it depended on Fano, as expressly declared in the census of the 1708. The investigation 1736 censuale introduces him more detailed: Sorbolongo is nominated twice you, in how much its territory results divided between the State of Urbino and the Province of the Brand. Among the places of the Urbinate it appears in fact the parish of S. Maurice, partly Diocese of Fossombrone; among the places of the Brand instead Sorbolongo is sued, belonging to the Diocese of Fossombrone but inclusive in the Contado of Fano. After the brief Napoleonic occupation, during which it was center of Commune, it returned, with the Restoration, under the government of the Pontifical and united State what appodiato to the Commune of S.Andrew of Suasa. From the unification of the Kingdom of Italy (1861) it was still center of Commune up to 1928 when it became fraction of S. Ippolito. It belongs to the Diocese of Fossombrone today that, in the recent ecclesiastical restructuring, you has been united to Fano the person of the same Bishop.
