The following outline is provided as an overview of and topical guide to San Marino:
San Marino – small sovereign country located in the Apennine Mountains on the Italian Peninsula in Southern Europe.[1] San Marino is a landlocked enclave, surrounded by Italy. One of the European microstates, San Marino has the smallest population of all the members of the Council of Europe and the 3rd highest GDP per capita in the world.
San Marino claims to be the oldest constitutional republic in the world, founded on 3 September 301, by Marinus, a Christian stonemason fleeing the religious persecution of Roman Emperor Diocletian. San Marino's constitution, dating back to 1600, is the world's oldest written constitution still in effect.[2]
