The City of San Marino is the national capital of which country, even though Serravalle is its most populous municipality?

Բացատրություն

San Marino is the country whose national capital is the City of San Marino. Serravalle has more residents, but population rank does not give that municipality the national-capital role. San Marino is a sovereign state in its own right, not part of Italy, and Monaco is a different city-state.
