Landlocked San Marino is one of the world's smallest countries. Surrounded by Italy, it is an echo from an era when city-states proliferated across Europe.

Mount Titano, part of the Appennine range, dominates San Marino's landscape. Three defensive fortresses perch on Titano's slopes, looking out to the Adriatic coast.

San Marino is said to be the world's oldest surviving republic.

Tourism dominates the economy of the 61 square kilometre (23.6 square miles) republic, which plays host to more than three million visitors every year.

Postage stamps and coins - keenly sought by collectors - are important sources of revenue.
