Suspended over the azure sea and set amid legendary rose-filled gardens, this Gothic-style castle was once home to Lord Grimthorpe and a hideaway of Greta Garbo. Its transformation into an exquisite hotel in the 1990s created guest rooms ranging from palatial to cozy—we especially love the small Peony Room, the only one in the castle with its own terrace overlooking the bay. A newer wing has a bevy of options with sea and pool views. Furniture, artworks, and vintage
art books that belonged to the lord's daughter still grace the enchanting sitting room and 19th-century Music Room. The gourmet restaurant "Il Flauto di Pan" was awarded a Michelin star in 2012.
