Geography

San Marino is surrounded by Italy in Southern Europe, on the border between the regions of Emilia Romagna and Marche and about ten kilometres (six miles) from the Adriatic coast at Rimini. Its hilly topography, with no substantial naturally flat ground, is part of the Apennine mountain range. The highest point in the country, the summit of Monte Titano, is 749 m (2,457 ft) above sea level; the lowest, the Ausa River (ending in the Marecchia), is 55 m (180 ft). San Marino has no still or contained bodies of water of any significant size.

It is one of only three countries in the world to be completely surrounded by one other country. The other two are Vatican City, also surrounded by Italy, and Lesotho, surrounded by South Africa. It is the third smallest country in Europe, after Vatican City and Monaco, and the fifth-smallest country in the world.

The terrestrial ecoregion of Italian sclerophyllous and semi-deciduous forests lies within San Marino's territory. The country had a 2019 Forest Landscape Integrity Index mean score of 0.01/10, ranking it last globally out of 172 countries.
