This 18th-century palace designed by Sir John Vanbrugh, of Blenheim Palace fame, occupies dramatic grounds with lakes, fountains, gardens, and an adventure playground. Boat trips on the lake and kids' trails and quiz sheets make it a great family bet. Begun in 1699 for the 3rd Earl of Carlisle, Castle Howard has a striking facade topped by a painted and gilded dome, and, inside, a chapel with stunning 19th-century stained-glass windows by Sir Edward Burne-Jones. The many important paintings on display include a portrait of Henry VIII by Holbein and works by Rubens, Reynolds, and Gainsborough. On the grounds, the family mausoleum is by Hawksmoor.
