Legend There is also a legend explaining the foundation of the Chiojdu village. It speaks of a wealthy Transylvanian peasant named Chiojd who lost all his family and possessions in a fire and started to wander around the mountains. Once he arrived in the present-day location of the Chiojdu village, he decided to settle down. The beauty of the place helped him move away from the sadness of losing his wife and his home. He eventually married a woman named Bâsca and they had two boys, Chiojdu Mare and Chiojdu Mic and a girl named Chojdeanca, who went on to found the villages that kept their names. Architecture Chiojdu is a very representative area for the folk architecture of the Carpathians' curvature region.
