Castles in San Marino

The world's oldest republic, San Marino clings to three limestone peaks — the Three Towers of Mount Titano — and has maintained uninterrupted self-governance since the 13th century. Surrounded entirely by Italy, this UNESCO-listed microstate offers one of Europe's most unusual heritage experiences: a medieval fortress complex that is simultaneously a living national capital and the enduring symbol of seven centuries of democratic sovereignty.
