Saint-Jean-Cap-Ferrat, France: Gorgeous Palazzo, even better: 9 gardens
It makes more sense when you know that Baroness Ephrussi's last name was de Rothschild, de that Rothschild. And she married money, too.
When you wonder what the point of having money is, the Ephrussi de Rothschild Villa and Gardens in Cap Ferrat on the French Riviera gives a pretty darn satisfying answer. The house is done in various Louis eras (with pink as a leit-motif), has an extraordinary art collection (a Fragonard here, a Lancret there) and an equally impressive porcelain collection. You'd be happy enough to move in, if forced.
But it's the gardens that you'll probably remember most. There are nine of them in various styles – Provençal, Japanese, rose, and Spanish among them – several of which boast views of the Mediterranean – it's overwhelmingly lovely.
Recover at the tea room, or watch the next act of the new musical fountains to help you forget that you weren't born a Rothschild.
