Similarly to other European microstates, such as Monaco, Liechtenstein and Andorra  it’s a relic of a time when borders were formed based on the area that a cannon could reach from a city’s walls. Founded on the slopes of Mount Titano in 301 AD, this tiny republic has seen the rest of Europe consolidate around it, surviving attacks by other self-governing Italian city-states, the Napoleonic Wars, the unification of Italy, and two world wars. Today, it’s borders are entirely enclosed by Italy, making it one of only three countries in the world to be enclosed by another nation. It is the smallest independent state in Europe after Vatican City and Monaco and, until the independence of Nauru (1968), was the smallest republic in the world, at just 61 square kilometre (23.6 square miles). Tourism dominates the economy of modern day San Marino.  which plays host to more than three million visitors every year, while the republic is home to just over 30,000 people. Your hosts, as always, are Luke Kelly @thelukejkelly in Hong Kong, Mark Boyle @markboyle86 in the UK, and Joe Byrne @anbeirneach in Switzerland . (Theme music by Thomas O'Boyle @thatthomasfella)
