Gerano

Gerano is a "comune" (municipality) in the Metropolitan City of Rome in the Italian region Latium, located about east of Rome.
History.
The year of foundation of Gerano is unknown; however, it is known that in 1005 it constituted a "castrum". In the Middle Ages, due to its strategic and economic importance, as the capital of "Massa Giovenzana" (replacing the more ancient "Trellanum"), for a while, Pope Gregory VII was interested in it, who in 1077 confirmed Gerano to be divided between the diocese of Tivoli and the abbot of Subiaco.
