Founded around 1125 by the Lord Thuring von (of) Lutzelfluh on his property in the valley of Trub to the honor of the Holy Cross and the evangelist John. He established the charitable work with estates in the region and placed it under the Benedictine monastery of St. Blasien in the Black Forest. Even though the Abbot of St. Blasien accepted the responsibility from the founder, the monastery Trub was filled by Benedictine monks from other places. They chose their own Abbot. The monastery estates were run by "God's house people" (familia sanctorum). These were freemen or serfs, free tax-payers, servants, or officials. As Tribune, that is a representative of the Abbot of Trub, officiated as chairman of the court of Trub on July 4, 1462 "Clawin at Fankhaus", citizen of Bern and officer of Trub, the previously mentioned father of the two quarreling brothers, Clewin (Nicolas) Fanghuser and Hannsen (John's son) Fanghuser.
After the first monastery fire of 1414, the monastery received and kept the rare, beautiful seal which since the beginning of the 14th century they hung (affixed) on important documents. The impression carries the latin inscription: S. CONVENTUS . MONASTERII . SCE . CRUCS. IN. TRUOBA which is an abbreviated form of Sigillum Conventus Monasterii Sancta Crucis in Truoba. In English: Seal of the Convent of the Monastery of the Holy Cross in Trub.
