San Marino is a landlocked microstate in Southern Europe, entirely surrounded by Italy on the northeastern slopes of the Apennine Mountains. At just over 61 square kilometers it is the fifth-smallest country in the world. It claims a traditional founding date of AD 301, making it, by its own account, the oldest extant sovereign state. Its capital, the City of San Marino, sits atop Monte Titano.
