According to the legends, a massive cannon, made by a man named Orbán/Urbán of Transylvanian origins, took a great part in the siege of Constantinople led by Mehmed the Conqueror. This engineering miracle of the time is mentioned in many resources, but we do not have exact knowledge about the person and origins of Orbán. However, Turks remember him as a Hungarian even today, thus a 2.8 m high wooden memorial was placed to commemorate him in the village of Demirköy, close to the city of Kırklareli, carved by Csaba Török. Demirköy was chosen because the forge where the huge cannon was made once was located within the boundaries of this settlement.
