On the edge of Lake Wörth, in a pocket of the Carinthia region known as the Austrian Riviera, Schloss Velden has lived many lives. It began in 1603 as a manor house and was rebuilt in 1890 as a turreted château. In 2007, Horst Schulze, the former vice chairman of Ritz-Carlton and the head of upstart luxury brand Capella Hotels & Resorts, turned the mansion into a 39-room hotel, adding a Jabornegg & Palffy–designed, glass-walled annex for another 66 rooms. He’s on to something: rain-forest showers, double-sided fireplaces, Pratesi linens, and a private assistant who phones guests ahead of time to make sure they get anything they want. Macrobiotic food? Pillows stuffed with fresh mint leaves? These are not empty promises.
