ბანი [bani] roof
Bani  is the Georgian word for a house roof: it has no tiles, it has no gutters, it has no skylights. Bani  is a flat roof of tamped earth, a sort of terrace which over the centuries has become very widespread in both the villages and the towns of eastern Georgia.
Architecture has always been a basic element in Georgia’s national memory.  You could write the history of Georgia on the basis of the architecture in its territory as you follow the great trade routes from east to west, on one branch of which Georgia is situated. Bani is one of these structures. 
On one side the Islamic world, on the other the Byzantine, and between them is Georgia. Over the centuries Georgian architecture has incarnated these three different styles. European architecture appeared in Georgian in the nineteenth century and was imbued quite naturally with a Georgian nuance.
In order to have a good bani, you need to have a lot of wooden supports: whole tree-trunks, squared joists, small branches.
In Georgia, where everyone’s neighbour knows what you had for dinner, the bani is a special means for communing. Thanks to the climate, people spent most of the year and the daytime on the bani. This is what has made neighbourly relations so free and easy.
Georgian architecture has been a visual reminder of existence, functioning just like literature and song in fortifying people’s life style and culture.
