This pink castle, built between 1679 and 1689 in a parkland ringed by wild hills, is the seat of the dukes of Buccleuch and Queensberry. It's home to some outstanding paintings, including a famous Rembrandt and a Holbein, plus relics related to Bonnie Prince Charlie. In 2004, the castle made headlines around the world when two thieves, posing as sightseers, overpowered a castle guard and made off with the Madonna with the Yarnwinder, believed to have been an important work by Leonardo da Vinci. Valued at $50 million, this painting was proclaimed by the National Gallery of Scotland as an authentic da Vinci in 1986, although skeptics remain. Even without da Vinci's Madonna, venerable works remain by Reynolds, Murillo, and other old masters, and the castle's architecture is splendid as well. There's a playground with amusements for kids and a working crafts center in the stable yard; the gardens are gradually being restored to their 1720 magnificence. Meals are served in the kitchen, which is hung with gleaming copper.
