Darbazi

Darbazi (Georgian: დარბაზი; from Persian: darvāze, "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.

[2][3] The darbazi house, with local variations, continued to be constructed into the 20th century in Georgia.

These houses are often supported at its underground base by finely carved beams and pillars, in particular, the solid wooden upright known as the deda-bodzi ("mother-pillar") that takes the weight of the corbelled roofing.
