In the heart of Italy, on the border between Emilia Romagna and Marche, the Republic of San Marino covers 61.196 km².
It is the third smallest country in Europe, behind only the Principality of Monaco and the Vatican City.
Monte Titano with its three “feathers” represents the symbol of the country. It marks the beginnings of the Tuscan-Romagna Apennines and, at 755 meters above sea level, is the highest point in the country. In fact, the mountain has an unusual configuration for the surrounding area, which is predominantly hilly. It is, in fact, a limestone-arenaceous rock, a remnant of the shattering twenty million years ago of a large submarine plate. Other fragments, on the other hand, gave rise to the mountains now known as Della Verna, Simoncello, Fumaiolo, and San Leo.
A number of streams originate from the Monte Titano and flow through San Marino territory and reach the rivers Marano and Marecchia, which, after a little more than twenty kilometers, flow into the Adriatic Sea: the former in Riccione, the latter in Rimini.
The Marano river originates at the border of the Republic of San Marino, from Mount Ghelfa, and flows through Montegiardino and Faetano.
The Rio San Marino originates in the Marche region and flows through the castles of Fiorentino, Chiesanuova and Acquaviva.
The Ausa originates on the slopes of Mount Titano, where it is called Fosso della Flocca, and flows through Serravalle, Domagnano and Borgo Maggiore.
Fiumicello originates in the Republic: the distance from Fiumicello, a tributary of the Marano, to Molino Frati in Acquaviva, is the widest stretch of San Marino territory: 8.75 km.
The lowest point in the country is at Falciano, Serravalle locality, 55 meters above sea level.
Borders of San Marino
The Republic of San Marino borders two Italian regions: to the south and west with Marche (province of Pesaro), to the north and east with Emilia Romagna (province of Rimini).
In total, the border with Italy is 39 km long.
