San Marino (City of San Marino, officially Città di San Marino) is the capital.
There are also eight minor municipalities:
Acquaviva
Borgo Maggiore
Chiesanuova
Domagnano
Faetano
Fiorentino
Montegiardino
Serravalle
The largest town of the Republic is Dogana, which is not an autonomous castello, but rather belongs to the Castello of Serravalle.
In a similar way to an Italian comune, each castello includes a main settlement, called capoluogo, which is the seat of the castello, and some even smaller localities known as frazioni.
