The Republic of San Marino comprises nine castelli (lit.

'castles') as its first-level administrative divisions.

[1] Each castle is led by a castle captain (Italian: capitano di castello) and a castle council (giunta di castello), elected every five years.

[2] Like Italian comuni, each castello has a capital (capoluogo), with other population centres sorted into curazie (equivalent to Italian frazioni).
