The Borromeo family began transforming this rocky islet in 1632, when Count Carlo III ordered a palace and garden built for his wife Isabella, whose name the island still carries. Four generations later, Vitaliano VI Borromeo had raised ten terraces of clipped hedges and citrus above the lake, shaped like the prow of a Baroque galleon and stocked with white peacocks that still patrol the parterres.
Napoleon and Josephine slept in the palace in 1797, and a plaque in the Sala Napoleonica marks their room. Inside, the Hall of Mirrors and a warren of artificial grottoes lined with shells and pumice offer relief from the sun before you climb back out among the statues.
