query: Who designed Blenheim Palace?
passage: Blenheim Palace
The architect selected for the ambitious project was a controversial one. The Duchess was known to favour Sir Christopher Wren, famous for St Paul's Cathedral and many other national buildings. The Duke however, following a chance meeting at a playhouse, is said to have commissioned Sir John Vanbrugh there and then. Vanbrugh, a popular dramatist, was an untrained architect, who usually worked in conjunction with the trained and practical Nicholas Hawksmoor. The duo had recently completed the first stages of the Baroque Castle Howard. This huge Yorkshire mansion was one of England's first houses in the flamboyant European Baroque style. The success of Castle Howard led Marlborough to commission something similar at Woodstock.[15]

In 1867, the young king Ludwig II had traveled to France but had to return to Bavaria when he heard of the death of his uncle Otto, without the opportunity to visit the Palace of Versailles. He nevertheless was concerned with the residence of King Louis XIV of France and had plans for a similar retreat drafted by his court architect Georg von Dollmann (1830–1895). A possible building site was chosen in the Graswang valley near Ettal, the later site of Linderhof Palace.
