Fortaleza Do Guincho

A 17th-century fortress on a windswept headland near the westernmost point of mainland Europe, converted into a luxury hotel where the Atlantic crashes against the cliffs below your window. Standard rooms peek at the ocean through narrow fortification slits, while suites open onto balconies with thick limestone walls and vaulted ceilings doing their part to make a dramatic argument. Pack a jacket: Guincho is famous for its wind, and the hotel leans into that fully.
