The Villa Carnignac art gallery is located on a Mediterranean island off the French Riviera called Porquerolles. Purpose-built to show off billionaire hedge-fund executive Edouard Carnignac’s modern art collection, the gallery opened in June. Monsieur Carnignac hung out at the Factory with Andy Warhol in the 1960s, is a freedom-loving, polo-playing child of the counter-culture who famously paid for an advertisement displayed in the leading papers of Europe on the same day urging former president Hollande to lay off taxing the rich.
