A team of UNESCO experts is visiting Oradea and Arad these days in order to identify the buildings and sites to join the world heritage list. The two Romanian districts intend to apply to the UNESCO world heritage, given the buildings and sites of special importance they house. According to Mihai Groza, a mayor of Oradea, both cities, which developed in tandem in 1900-1914, are standing great odds to achieve this. Bernd von Droste, UNESCO consultant, claims the difficulty is to detect what is unique and of international importance and he adds that, if something is not on the UNESCO list, it doesn't mean that something is unworthy. According to the official, the UNESCO is not very rich in financial funds and it keeps the list as short as possible. Architect Cristiana Iamandei explains there are two main criteria for a building to reach the world heritage: to be unique and well preserved. "Unfortunately, the preservation of sites in Oradea is poor", she comments. Here are those Romanian treasures right now part of the UNESCO world heritage: 7 Transylvanian sites including fortified churches, the Hurezi Monastery, 7 Moldavian churches, the historical center of Sighisoara, the wooden churches in Maramures, the Dacian fortresses in the Orastie Mountains and the Danube Delta reserve.
