The name Terento is taken from the Latin word “torrentum“ meaning mountain torrent. It was first mentioned in an ancient book of the Freising Monastery. Earl Otto from Andechs entrusted four of Terento`s farms (“in monte Torento hobas IIII“) to Bishop Gottschalk of Freising. This mention of the village dates back to the time between 994 and 1005. Around the year 1000 „mons Terrentum“ was first mentioned. It is certain though, that Terento was already populated in prehistoric times. This can also be proved thanks to certain findings and the remains of walls at places like St. Zeno, Pflanger and Pürgstallkopf. Aswell as this, the so called “Hexenstein“ (witches stone), a shell stone in the Winnebach Valley is more than likely a prehistoric source of sanctum. Dating back to the beginning of the 7th Century with the conquering by the Bajuwari, the ancient Bavarians, settlements expanded. Most of the single farm settlements are likely to date back to this time. Up to the 12th Century Terento was part of the Norital Shire. Following the seperation of the then existing courts, Terento switched over from the Rodengo Court to the Schöneck Court.
