Porta Soprana shared by @afar says: ""Swallow your fear of heights Just remember that these towers have been standing since 1163. They probably won't fall today! But even if you have a fear of heights, do pay the 2 euro to walk up the beautiful interior circular staircases in these ancient towers of the Barbarossa walls (the second recorded expansion of the old city). The views of the mountains at sunset are spectacular."" on Postcard
