On the ruins of an abandoned medieval town — towers, roofless churches, a Roman bridge — the Caetani family planted from 1921 a garden the New York Times would call the world's most beautiful and romantic: roses climbing the ruins, maples and magnolias along a transparent river that keeps the same temperature year-round, cherry trees snowing petals onto the water in April.
It is a natural monument open only on counted dates, with limited numbers and guided visits: fragility is its rule.
Our tip: online tickets sell out fast: book weeks ahead aiming for April-May, when roses and cherries overlap. No picnics, no hurry: Ninfa is crossed at poetry's pace.
