San Marino shares Vatican City's identity as one of the world's smallest sovereign states, where the entire territory can be experienced as a single destination.

The compact scale creates an intimate encounter with state symbols and civic pride.

Monaco operates as a city-state microstate like Vatican City, where crossing invisible borders means entering an entirely different sovereign territory with its own identity.
