All Svansky towers look absolutely identical – a square (5 х 5m) tapered stone structure of 25 m height. Each tower has four or five levels with a windowed upper part. A tower was built on a slope with its edge on this slope. The massive hemisphere of the tower basis made it sturdy enough to withstand cataclysms. 
   The biggest number of Svan towers (few dozens) have survived in Mestia and Ushguli. The youngest one is at least two hundred years. Now the towers are not used, their wooden floor partitions collapsed long time ago so it is impossible to climb them.
