Sighnaghi, with only 2,100 people, is a mountain top architectural gem. Its name comes from the word siginak, Turkish for “shelter.” It was built in the 18th century as a fortified town on the frontiers of Moslem Azerbaijan and Dagestan. It main industries are wine making, carpet making and, now, tourism. The town is circled by about 4.5 kilometers of wall with 23 defensive towers. The wall winds around the mountain side. I walked along the top for about a half a kilometer between several of the towers with great views of vineyards running down the mountain.
