Svans lived in complete isolation until 1920s, the only nation in Caucasus that never was conquered by anyone.
Kodori gorge leads to Abkhazia low-lands from Teberda mountain region through Klukhorski pass. In 1942 3 Soviet mountain infantry regiments were stationed there (in fact they consisted of ordinary infantry without mountain training or equipment). Their HQ in a village of Azhary was attacked by German Edelweiss mountain-jagers. Very few Germans survived it, and IIRC it was the only time Germans crossed Grand Caucasus and invaded Svanetia.
I have crossed Klukhorski pass and went down to Azhary in 1990 with my Father. Azhary was a peacefull and very nice village with hundreds of hikers and alpinists. Now local guys that played checkers and drank wine with us probably shoot at the invaders... This world sucks

Local militants already got a promise from Abhazian defence ministry that Abhazia will help them with military force. Russian peace-keepers not involved yet.
So - another war already began. Watch it.
Here is the Northern side of the Kodori gorge, lake Kluhor.
Lower the mountains are covered with thick forest. Swans mostly live in Alpian meadows.
Here is a typical landscape with a Svan tower:

The tower is a traditional Svan fortress/castle, they stand there for maybe 1000 years, each one for a family/clan, in case off attack they stay there with all their cattle.
