Medieval Towers in the republic of Georgia. Some, apparently, were used as signal towers while most were family or clan-owned, and used as defensive structures during feuds and vendettas. When not in use during attacks, they could be used as barns or silos.
A little fun with animation. I made this for @DaveRubin in honor of his newly published book: "Don't Burn This Book" which, sadly, received a number of negative attention from trolls. Unsurprisingly, almost none of the negative reviews came from verified purchases. But, that's what haters do. They would rather destroy than build because they lack the ambition, the discipline, and the courage to create something worthwhile.
