The micro-nation is only 23.6 square miles.
There are a seemingly endless number of destinations and attractions to visit in Europe, both for newcomers and frequent visitors. From the Eiffel Tower in Paris to the Prado in Spain to the Swiss Alps, visitors could spend months touring around Europe and never see it all.
Which might explain why the gorgeous micro-nation of San Marino was the least visited country in Europe in 2016, according the United Nations World Tourism Organization (UNWTO).
Situated inside north-central Italy, San Marino is known for its stark mountain views and its three medieval fortresses. The three castles overlook spectacular views, and UNESCO named the historic center a world heritage site, in part for the "castelli."
Visitors can take a stroll along nearby beaches (which are technically in Italy) or through the historic town center before enjoying a meal of fresh pastas, roasted meats, and wines sourced from local vineyards.
Just 23.6 square miles in area, San Marino is one of the smallest countries in the world. It can be reached by a quick train or car ride from parts of Northern Italy.
