According to several authoritative historians such Peter Štih (cited above) and Camillo de Franceschi, this charter marks the very first mention of Lupoglav in historical sources. Thus, these historians believe that the castrum in Lupoglav could not have been built much earlier.
Other historians, including the editor, believe that the toponym "Lompaga" featured in Henry IV's donation charter to Margrave Ulrich (edited here) refers precisely to Lupoglav.
The problem with this interpretation is the fact that Lupoglav is certainly not mentioned in the Ulrich II's donation charter of 1102 to Patriarch Ulrich of Aquileia (edited here). This is the sole argument why De Franceschi and Štih refuse to identify "Lompaga" with Lupoglav.
However, the 1102 donation charter clearly states that Ulrich II bestows upon the Church of Aquileia his entire patrimony in Istria (excluding the four possessions that he had previously given to Maynard, Adalbert the Senior and Adalbert the Junior), and not only the places that he singled out: "and all that may be found in whatever other place belonging to us in this County, in cities as well as outside of them" ("vel per aliis quibuscumque locis invenire potueritis de nostris iuris rebus in eodem Comitatu, tam in civitatibus quamque et de foris"). Lupoglav would thus simply be one of the possessions that Ulrich (or the scribe) forgot to mention (or write down) but that was nonetheless donated to the Church of Aquileia by way of the aforementioned clause.
Be that as it may, Lupoglav officially ceased to be a possession of the Patriarchate of Aquileia after this investiture by which Patriarch Gregory relinquished the fort and the village in its district, along with other properties in the Karst region and in Carniola, to knight Henry of Pazin, a loyal ministerial of the counts of Gorizia.
Why did he do it? The most obvious answer is that the patriarch tried to establish amicable relations with both the counts of Gorizia and their loyal followers in Istria in order to build up his forces following the signing of the Treaty of Buzet (to be edited here presently). The plan failed and backfired.
