Darbazi (; from , "gate") is a term used in Georgia to describe a chamber with a distinctive "swallow dome"-type roof structure found in the traditional domestic architecture of Asia Minor and the South Caucasus. The central feature is a pyramidal vault (gvirgvini), supported on pillars and constructed of a stepped series of hewn logs and beams, with a central opening at the top which serves as a window and smoke flue. The Roman authority Vitruvius (1st century BC) includes in his De architectura a description of a Colchian dwelling, the ancient prototype of a darbazi. Such lantern roofs are called harazashen or glkhatun in Armenia, kirlangiç kubbe or kirlangiç ortu in Turkey, and karadam in Azerbaijan.
