Patriarch Ulrich I of Aquileia completes the foundation of the monastery of Moggio begun by his predecessor Frederick at Count Kazelin’s request, endowing it with the count's allodial properties and adding his own donations, including Oprtalj and the mills in Lim Bay in Istria.
Patriarch Peregrine I of Aquileia confirms the foundation and possessions of the monastery of Saint Gall in Moggio, originally donated and endowed by Patriarch Ulrich I with properties bestowed by Count Kazelin, adding further privileges, tithes, and jurisdictional rights, and prohibiting their alienation or infringement under threat of anathema.
Ulrich II, patriarch elect of Aquileia, exchanges properties with Abbot Ulrich and the St. Gall’s Monastery of Moggio, bestowing the estate that was previously held in fief from the Patriarchate of Aquileia by a certain Vetradis, wife of Eckbert, at San Canziano and from Fiumicello to the Karst, and receiving Oprtalj in Istria in return. Following the death of Vetradis, Ulrich II, patriarch elect of Aquileia, confirms the exchanged property to the monastery and establishes an anniversary for himself and his predecessors.
