Located in the coastal village of St. Mawes, the Hotel Tresanton is a converted yacht club overlooking the Fal Estuary, which is notable for a pair of matching castles built by Henry VIII on either shore. Overhauled by Olga Polizzi of the Forte Hotel clan, the Tresanton is actually a cluster of small buildings set into a hillside; the interiors feature a maritime theme without being heavy-handed, and rooms are furnished with antique pieces, Welsh blankets, and Cornish art.
