A Christmas Prince was filmed on location in Romania, specifically in the capital city of Bucharest and the Transylvanian region. The movie's main settings, such as the castle where the royal family resides, were recreated on soundstages in Bucharest. Additional scenes were filmed in the fortified village of Viscri and the picturesque town of Sighisoara, both known for their well-preserved medieval architecture. The stunning landscapes of Transylvania, with its snow-covered mountains and lush forests, provided a stunning backdrop for the movie's magical Christmas setting.
