313. San Marino, San Marino
313. Oh my, why not? I was pretty amazed by what I saw when I visited. The Republic of San Marino is a principality within Italy. The center of the region sits at the top of a mountain. It will take you some time to explore it all, but its totally worth it. Did I mention the unprecedented view? Especially when it rains. Plus, its a UNESCO World Heritage Site as well.
