The Cathedral of the Assumption of the Blessed Virgin Mary and Saint Stephen and Ladislaus or the Zagreb Cathedral is the largest Croatian sacral building and one of the most valuable monuments of Croatian cultural heritage.
The bishopric of Zagreb was established by king Ladislaus in 1094 and he subsumed it to the archbishopric in Ostrogon [2]. In the same year, so the Croatian tradition, the cathedral was established. There's no unanimous view considering the question of who was to establish the bishopric – was it Ladislaus who actually commissioned to build the cathedral or some other existant church served this purpose instead. One also presupposes that this could have been a benedictine church that belonged to its monastery. One of the arguments against this theory is that which claims king Ladislaus its establisher, arising from the fact that the king had died only a year after the cathedral was established. It is held that it's precisely because of this that he had not enough time on his hands to finish the plan. More important is the fact that there's no mention of his contibution to the construction of the cathedral in archbishop Felicius's charter, who would have surely noted such a thing.
